EARTHWORK
SECTION 201 - CLEARING AND GRUBBING
201-1 DESCRIPTION
201-1.01 General. This work shall consist of clearing, grubbing, removing and disposing of all trees,
brush, stumps, fences, debris, and miscellaneous structures not covered under other contract items within
the construction area and such other areas as specified or directed. The Contractor shall clear such
additional areas within the limits of the right-of-way and easement lines as specified or directed.
201-1.02 No Burning Requirement. Materials generated by the work, including construction and
demolition debris, shall not be disposed of by burning on or off the site. Off site burning in a permitted
solid waste incinerator or in another lawful manner as refuse derived fuel will be permitted.
201-2 MATERIALS (Not specified)
201-3 CONSTRUCTION DETAILS
201-3.01 Limits of Work Areas. The Engineer will establish the limits of areas to be cleared and
grubbed, to be cleared but not grubbed, or areas, objects or features that are designated to remain
undisturbed. In general, the work areas shall include the road section, stream channels, ditches, temporary
approaches to bridges, detours and other areas as shown in the contract documents or directed by the
Engineer. The Engineer will designate fences, structures, debris, trees and brush to be cleared where
grubbing is not required. Clearing beyond the areas of construction shall be done only where specified or
directed.
201-3.02 Clearing and Grubbing. During the life of the contract the Engineer may order the clearing of
any trees within the R.O.W. that the Engineer determines to be hazardous or dead and unsightly.
The Contractor shall carefully prune all branches of trees less than 16 feet above any part of the
roadway and all branches which have been broken or injured during construction. The work shall be done
as specified under §614-3.01A Equipment and B. Pruning.
Whenever trees are felled or trimmed on/or adjacent to highways, all wood shall be immediately
removed from the roadway or any area that would present a hazard to traffic. Grubbed stumps shall be
moved immediately at least 30 feet from the edge of pavement. No trees, tree trunks, stumps or other
debris shall be felled, sidecast or placed outside the limits of the road section. No grubbing will be
required beneath the embankment where the finished grade will be 6 feet or more above the original
ground surface unless otherwise specified in the contract documents. Where trees or existing stumps are
cleared and grubbing is not required, the tree trunk or existing stump shall be cut off not more than 6
inches above the original ground surface unless otherwise approved. Exposed stumps not required to be
removed, but which are within 30 feet of the edge of the pavement or are in a built-up area, shall be
5 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
chipped out to a depth of not less than 6 inches below the finished grade and the holes backfilled if
directed by the Engineer. This work shall be completed within one week after start of work on the tree.
201-3.03 Disposal
A. General. All wood including grubbed stumps shall be removed from the contract site or otherwise
disposed of.
B. Methods of Disposal of Wood and Brush.
1. Disposal (No Burning). All wood and brush shall be disposed of within fifteen (15) days after
cutting or felling unless otherwise approved. No burning of land clearing materials that result
from the clearing and grubbing operations, except in a permitted solid waste incinerator or as
refuse derived fuel, will be permitted. The Contractor will have the following options or
combination of options for disposal of this material:
a. The Contractor shall make every effort to salvage marketable timber as specified in paragraph
B4 of this subsection.
b. When permitted by a note in the contract documents, disposable material may be placed at
locations approved by the Engineer within the right-of-way but outside of the embankment area.
When permitted by a note in the contract documents, disposable material may be placed in
the embankment side slope area. The contract documents will define the embankment side slope
area and the procedures for the concurrent construction of the embankment and disposal section.
This type of disposal will require certain preparatory work. Preparation for direct burial of
woody materials shall consist of cutting main trunks and limbs and chipping smaller limbs,
branches, foliage and brush. Under conditions when disposal space and earth cover are limited in
size and quantity, stumps will have to be ranked in size and placed in layers so as to make best
use of the space available and the quantity of materials to be buried.
c. The Contractor may bury disposable material off the right-of-way at locations obtained by the
Contractor at no expense to the State. Such locations are to be approved in writing by the
Engineer. The disposal work will require the same preparatory work as stated in option b. above
except that the Engineer may waive such requirements for miscellaneous work which may be
accommodated in a satisfactory manner by other methods. The disposal area is to be covered with
earth as hereinafter specified.
d. The Contractor may reduce all woody materials to chips and dispose of the chips as specified
in paragraph B2 of this subsection.
e. The material may be sent to a refuse derived fuel processing facility or to other processing
facility for eventual beneficial re-use as fuel or for other lawful re-use.
Under no circumstances is disposal to be made in swamp or wet lands. When the disposal
area is within the embankment section or is formed by flattening the embankment slopes, the
elevation of the normal embankment construction shall always equal or exceed that of the
disposal area. There is to be absolutely no end dumping of disposable material over the sides of
the embankment. All disposal areas are to be finally covered with a minimum of 2 feet of earth
and graded to drain properly.
2. Chipping. Wood may be reduced to chips by the use of an approved chipping machine or
stump grinder. Chips shall be 1/2 inch maximum thickness or of other approved thicknesses.
6 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Chips resulting therefrom may be disposed of by being stockpiled and used as mulch for planting,
by distribution on the ground surface in wooded areas within the right-of-way as approved by the
Engineer, or by disposal at a location off the contract site satisfactory to the Engineer.
3. Burying. No tree trunks, stumps or other debris shall be buried inside the right-of-way limits
without the written approval of the Engineer. Disposal areas outside the right-of-way limits shall
be approved in writing by the Engineer and shall be acquired by the Contractor at no expense to
the State.
4. Salvage of Marketable Timber. In the interest of conservation, the Contractor shall make every
effort possible to salvage marketable timber produced as a result of clearing operations, provided
the amount of timber is great enough to make the hauling practical. In general, marketable timber
is construed to mean logs 8 to 16 feet in length, plus appropriate trimming allowance, having a
diameter inside the bark, at the small end, of approximately 10 inches. In the event that the
Contractor is not successful in salvaging marketable timber, the Contractor shall advise the
Engineer, in writing, of the efforts to salvage and indicate the reason why the timber could not be
salvaged.
Any wood that is cut up in firewood lengths or other marketable lengths may be neatly piled
adjacent to the right-of-way in an area provided by the Contractor for periods in excess of one
week but shall be removed prior to completion of the contract.
201-4 METHOD OF MEASUREMENT
201-4.01 Per Acre. Payment for Clearing and Grubbing will be made at the unit price bid per acre
computed to the nearest one tenth acre.
201-4.02 Per Lump Sum. Payment for Clearing and Grubbing will be made on a lump sum basis for
work satisfactorily completed. Monthly payments will be made in proportion to the amount of work done
as determined by the Engineer.
201-4.03 Borrow Areas. Borrow pits or other pit areas from which material is secured shall not be
included for measurement of clearing and grubbing.
201-5 BASIS OF PAYMENT.
201-5.01 Clearing and Grubbing. Payment will be made at the contract price to furnish all materials,
labor and equipment necessary to satisfactorily complete the work as specified. No separate payment will
be made for any excavation, backfill or earth cover necessary to complete the work of disposal outside the
embankment area nor for the work in handling, storing, rehandling and hauling of disposable material
within or outside the right-of-way.
Payment will be made under:

SECTION 203 - EXCAVATION AND EMBANKMENT (Last Revised January 2020)
203-1 DESCRIPTION. This work shall consist of excavation, disposal, placement and compaction of all
materials that are not provided for under another section of these Specifications, and shall be executed in
conformance with payment lines, grades, thicknesses and typical sections specified in the contract
documents.
203-1.01 Definitions.
A. Unclassified Excavation. Unclassified excavation shall consist of the excavation and disposal of
all materials, of any description, encountered in the course of construction, unless otherwise specified
in the contract. Estimated limits and descriptions of subsurface deposits and formations which may be
shown in the contract documents are supplied as a part of Base Line Data.
B. Embankment. The embankment is the portion of a fill section situated between the embankment
foundation and the subgrade surface, excluding any material placed under another section of these
specifications.
C. Embankment Foundation. The embankment foundation is the surface upon which an
embankment is constructed after all work required under §203-3.03A. Embankment Foundation has
been completed.
D. Subgrade Surface. The subgrade surface is the surface of the road section upon which the select
materials and/or subbase are placed.
E. Subgrade Area. The subgrade area is that portion of an embankment situated above either of the
following, but excluding any material placed under another section of these specifications.
18 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
1. A line located 2 ft. below the subgrade surface and extended to the intersection with the
embankment side slopes, or
2. The embankment foundation, whichever is higher.
The material and compaction requirements for the subgrade area in embankments are found in
§203-2.01A. Subgrade Area Material and §203-3.03C. Compaction, respectively.
In cut sections, the subgrade area is not defined except where undercut and backfill with a select
material item is specified or ordered: in such cases, the payment lines for undercut work shall define
the subgrade area.
F. Embankment Side Slope Area. The embankment side slope areas are those cross-sectional areas
of an embankment situated outside of lines projected downward and outward on a one on one slope
from the edges of the subgrade surface to their intersection with the embankment foundation, but
excluding any portion lying within a subgrade area.
G. Topsoil. See Section 713 Topsoil.
H. Suitable Material. A material whose composition is satisfactory for use in embankment
construction is a suitable material. The moisture content of the material has no bearing upon such
designation. In general, any mineral (inorganic) soil, blasted or broken rock and similar materials of
natural or man made (i.e. recycled) origin, including mixtures thereof, are considered suitable
materials. Contaminated material is not considered suitable. Determinations of whether a specific
natural material is a suitable material shall be made by the Engineer on the above basis.
Recycled materials that the Department has evaluated and approved for general use shall be
considered to be suitable material for embankment construction subject to the conditions for use as
determined by the Department. The Regional Geotechnical Engineer and Geotechnical Engineering
Bureau are available to provide guidance on the use of such materials. In general, the use of recycled
materials must be also sanctioned by the Department of Environmental Conservation, usually in the
form of a Beneficial Use Determination (BUD).
Glass from recycling facilities meeting the requirements of §733-05 Glass Backfill shall be
considered suitable material for embankment construction.
Reclaimed Asphalt Pavement (RAP), and Recycled Portland Cement Concrete Aggregate (RCA)
shall be considered suitable materials for embankment construction, subject to the following
conditions for use:
RAP - The Contractor shall provide and place RAP conforming to the requirements of §733-06
Reclaimed Asphalt Pavement for Earthwork and Subbase.
RCA-The Contractor shall provide and place RCA conforming to the requirements of §733-07
Recycled Portland Cement Concrete Aggregate.
Pieces of broken up concrete pavement from on-site pavement removal or in-place recycling (i.e.
rubblizing, crack and seat, break and seat, etc.) may be used in embankment construction. Refer to
§203-3.03A. Embankment Foundation and §203-3.03B. Embankments.
I. Unsuitable Material. Any material containing vegetable or organic matter, such as muck, peat,
organic silt, topsoil or sod, or other material that is not satisfactory for use in embankment
construction under §203-1.01H. Suitable Material is designated as an unsuitable material. Certain
man made deposits of industrial waste, toxic or contaminated materials, sludge, landfill or other
material may also be determined to be unsuitable materials, based on an evaluation by the
Department’s Geotechnical Engineering Bureau and Office of Environment, and the Department of
Environmental Conservation.
19 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
J. Borrow. Borrow is material required for earthwork construction in excess of the quantity of
suitable material available from the required grading, cuts and excavations. Borrow may be necessary
even though not shown in the contract documents.
K. Embankment Construction Control Devices. Embankment construction control devices allow
real-time observations of embankment construction to assess the actual performance of the
embankment compared to that envisioned in the design phase. Settlement and pore water pressure are
common measures of embankment performance. Techniques for monitoring settlement include a
settlement rod or a surface settlement gauge. A settlement rod is an optical survey technique to
monitor settlement of the embankment surface. The settlement rod(s) establish monitoring point(s) in
relation to a reliable bench mark.
A surface settlement gauge is an optical survey technique to monitor settlement of the existing
ground surface, below the embankment installation. The surface settlement gauge is installed prior to
placing the embankment and extended upwards through the fill.
Pore water pressure monitoring may be used to determine the effective overburden diagrams (the
basis of all geotechnical analyses), monitoring consolidation progress of embankments constructed
over soft soils, evaluating seepage in natural slopes or earth dams (slope stability), checking the
effectiveness of subsurface drainage facilities, or monitoring water well tests.
A piezometer is an instrument which provides measurements of pore water pressure at the
elevation of the installed sensor. Pore pressure data is needed in a foundation soil to assess the excess
pore water pressure and hence the undrained strength of the soil. Piezometers are used at various
depths within cohesive foundation soils. Some piezometers are used in granular foundation soils to
assess their drainage behavior.
L. Proof Rolling. Proof rolling consists of applying test loads over the subgrade surface by means
of a heavy pneumatic-tired roller of specified design, to locate and permit timely correction of
deficiencies likely to adversely affect performance of the pavement structure.
M. Select Granular Fill – Slope Protection. Select granular fill – slope protection is a material used
to protect the grade of a slope from erosion and sloughing from runoff and groundwater seepage.
Seepage is the slow movement of water through small openings and spaces in the surface of
unsaturated soil into or out of a body of surface or subsurface water. Sloughing is a shallow surface
failure caused by erosive removal of supporting material.
Select granular fill – slope protection is highly permeable while also providing sufficient
frictional resistance to resist seepage forces and remain in place.
N. Applying Water. Under this work, the Contractor shall furnish and apply water for dust control.
Moisture control for compaction purposes is the Contractor’s responsibility. Water shall not be
applied in inclement weather or when the temperature is 32° F or less.
O. Modifying Cut Slopes and Other Means of Obtaining Borrow. The Regional Director may
approve the modification of cut slopes and other means of obtaining material, which is not part of the
contract, so long as provisions are made to prevent unsafe conditions, damage, and nuisances to
property, wildlife areas, and haul routes within and outside the contract limits. Such approval may be
granted only after review of a written proposal by the Contractor showing the final deposition of the
material, the haul route, hauling hours, and provisions necessary to comply with the above. Should
unanticipated conditions arise resulting in any unsatisfactory situation, the Engineer shall
immediately rescind the approval pending satisfactory correction.
The following procedure shall apply to areas within the R.O.W. limits which are not designated
as available sources of borrow by a Special Note in the contract proposal where the Contractor
requests and is granted permission to modify slopes to obtain material for use on State contract work
20 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
only. The Contractor will be required to reimburse the State with a rebate for the material obtained in
these areas. Permission will not be granted to excavate material beyond the design slopes if it is to be
used on other than State contract work.
The rebate to be obtained from the Contractor for this material is comprised of 1) A royalty based
on the actual value of the excavated material, and 2) A credit for the difference in the Contractor's
handling costs if these handling costs have been reduced. The royalty which is to be obtained for the
excavated material shall be appropriate for the item for which it is to be utilized and shall be
comparable to the current price being paid to purchase similar material in the area.
If the Contractor's handling costs associated with obtaining material from within the R.O.W.
limits are greater than those for obtaining material from other acceptable sources, these additional
handling costs must be borne by the Contractor. The royalty shall not be reduced to offset any
increased handling costs incurred by the Contractor.
If the Contractor's handling costs associated with obtaining materials from within the R.O.W.
limits are less than those for obtaining material from other acceptable sources, the differences shall be
reimbursed to the State as a credit in addition to the royalty.
The difference in the Contractor's handling cost shall be determined by an analysis based on a
comparison of haul lengths, hauling equipment, hauling operation, use of haul roads or public
highways, preparation and restoration of the borrow areas, and any other variables involved.
Prior to modifying rock cut slopes, the Geotechnical Engineering Bureau must be consulted. If
rock cut slopes are flattened sufficiently to eliminate the need for presplitting, an additional rebate
will be necessary.
All special requirements to be fulfilled by the Contractor, at the Contractor's own expense, shall
be clearly stated in the agreement. The foregoing requirement of receiving a rebate from the
Contractor for material obtained by modification of slopes shall apply only to locations not
designated in the Contract Documents.
P. Winter Earthwork. Compaction of soil during cold weather is difficult and can be impractical.
Water acts as a lubricant aiding in the process of compaction. As the temperature decreases, the water
becomes more viscous (less slippery) and inhibits efforts to pack the soil particles together.
Eventually, the water becomes ice, at which point compaction is impossible. For this reason, New
York State does not permit normal earthwork placement between November 1st thru April 1st unless
there is an approved Winter Earthwork submittal.
Winter Earthwork is defined as construction operations requiring soil compaction performed from
November 1st thru April 1st. The execution of Winter Earthwork requires modifications to compaction
procedures, changes to material requirements, and/or additional equipment and structure assembly for
controlling the weather effects on the material and existing ground conditions.
Although Winter Earthwork may be performed when the air temperature, ground temperature, or
material temperature is at or below 32° F, frozen material will not be placed, nor will fill material be
placed on ground frozen to any depth, in any work incorporated into the final product

203-3 CONSTRUCTION DETAILS
203-3.01 General. The Contractor shall remove all soil, rock, and other material, and utilize or dispose of
these materials as required by the contract documents. All excavation and embankment work shall be
executed to payment lines shown in the contract documents.
All graded earth surfaces outside the roadway limits shall be smoothed and trimmed in reasonably
close conformity (6± in.) of true grade. After trimming, the area shall be left in a compact and satisfactory
condition, free of large stones or other objectionable materials, as determined by the Engineer.
Earthwork construction operations requiring compaction shall not be performed from November 1st
thru April 1st except with a Winter Earthwork submittal subject to the provision of this Section and
approved by the Regional Director or his designated representative. Winter earthwork operations
constitute an additional risk to the Department and Winter Earthwork submittals should not be expected
to be automatically approved. Winter Earthwork will be subject to the following restrictions:
● Transitioning from the normal construction season to the exempt winter earthwork months
between November 1st and April 1st, the use of standard earthwork materials may be permitted only
under the conditions where the air temperature, ground temperature and material temperature are all
above 32° F at the time of placement. Modifications to compaction procedures, including but not
limited to the use of thinner lifts, may be required when the temperatures are above 32° F but below
40° F at the time of placement.
● Between November 1st and April 1st, if the air temperature, ground temperature, or material
temperature is at or below 32° F, earthwork may only proceed using material that meets the
requirements of §733-16 Winter Earthwork and/or standard earthwork material placement utilizing
the modified methods and procedures contained in the approved Winter Earthwork Submittal.
23 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
In all work incorporated into the final product, the Contractor shall not place material that is frozen,
or place fill material on ground that is frozen to any depth regardless of the date.
A. Winter Earthwork Submittal. For Contractors choosing to proceed with earthwork construction
operations requiring compaction between November 1st thru April 1st, provide the Engineer with a
Winter Earthwork submittal, with a copy to the Regional Geotechnical Engineer, outlining the
modifications to the materials and/or methods including the following:
1. Material Requirements. The material meets the requirements of §733-16 Winter Earthwork.
Provide information on material composition and source substitute, if proposed.
2. Material Placement. Provide information on the proposed methods for controlling the weather
effects on the material and existing ground conditions (i.e. insulation, enclosures, canvas and
framework). Devise a plan to be outlined in the Winter Earthwork Submittal such that all snow,
ice, and frozen material shall be removed from the surface of the ground on which embankment
or backfill material is to be placed, and from the surface under construction before succeeding
lifts are added.
3. Procedures. Provide verification procedures to ensure the existing ground is not frozen to any
depth (e.g. test pits). Provide procedures to address freeze-thaw action in earthwork that has
remained idle during temperature fluctuations (e.g. re-roll and seal the surface prior to placement
of succeeding lift).
4. Seasonal Adjustment Acceptance. Provide acknowledgement of a transition period allowing
the continued use of standard earthwork materials between November 1st and April 1st only under
conditions where the air temperature, ground temperature and material temperature are all above
32° F at the time of placement. Provide acknowledgement of the winter earthwork restrictions
stating that, if the air temperature, ground temperature, or material temperature is at or below 32°
F, earthwork will only proceed using material that meets the requirements of §733-16 Winter
Earthwork and/or standard earthwork material placement utilizing the modified methods and
procedures contained in the approved Winter Earthwork Submittal.
Proceed with Winter Earthwork only after receiving written approval by the Regional Director or
his designated representative subject to the provisions of this Section.
B. Scheduling of Work to Minimize Soil Erosion and Water Pollution. The Contractor shall ensure
effective and continuous soil erosion and sediment control throughout the construction period. The
Contractor shall prepare and submit for approval, plans and schedules for all excavation, stripping,
embankment, fill and grading operations. Such plans and schedules shall include but are not limited to
temporary and permanent erosion control measures specified in Section 209 Soil Erosion and
Sediment Control, Section 610 Turf and Wildflower Establishment and Section 612 Sodding.
C. Drainage and Grading. The Contractor shall provide and maintain slopes, crowns and ditches on
all excavation and embankments to ensure satisfactory surface drainage at all times. Ditches and other
drainage facilities necessary to remove ponded water shall be constructed as soon as practical to have
the work area dry during the progression of work. All existing culverts and drainage systems shall be
maintained in satisfactory operating condition throughout the course of the work. If it is necessary to
interrupt existing surface drainage, sewers or under-drainage, then temporary drainage facilities shall
be provided until the permanent drainage work is complete. Top-of-slope interceptor ditches, where
shown on the contract documents, shall be completed before adjacent excavation operations are
24 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
begun. In earth cuts, the Contractor shall progress excavation operations in such a manner that the
portion of the cut immediately adjacent to the design slope is at least 5 ft. lower than the general level
of the cut at all times until the lower payment line is reached.
The construction of these temporary drainage facilities shall be considered as incidental to the
construction of the project and no additional payment will be allowed.
Any portion of an embankment or subgrade which has been damaged by the Contractor's
equipment during the course of construction, shall be repaired and re-compacted by the Contractor at
no additional cost to the State.
Where seepage causes instability of slopes, excavation and backfill or other corrective measures
shall be performed as ordered by the Engineer and paid for under the appropriate item. Excavation for
the installation of slope protection may be necessary at any time and location throughout the duration
of the contract and may not necessarily coincide with the Contractor's performance of the general
excavation work.
D. Suitable Materials. Moisture content has no bearing on the suitability of material to be used for
embankment construction, however, the moisture content of a material may be such that its use will
require manipulation. It is the Contractor's responsibility to determine the economics of using, or
disposing of and replacing, such materials. Material determined by the Contractor to be un-
economical for use may be disposed of as specified under §203-3.02B. Disposal of Surplus Excavated
Materials and replaced with other material at no additional cost to the State.
When a contract includes the item “Unclassified Excavation and Disposal”, all excavated suitable
materials, including the excavation performed under “Structure Excavation” and “Trench and Culvert
Excavation,” shall become the Contractor's property for disposal or use under another item of these
specifications.
E. Unsuitable Materials. All excavated unsuitable materials shall be the Contractor's property for
disposal as surplus materials under the provisions of §203-3.02B. Disposal of Surplus Excavated
Materials.
F. Borrow. The management of a borrow source and the acceptability of all borrow material shall be
subject to the approval of the Engineer at all times. The Contractor shall notify the Engineer at least
ten (10) work days in advance of opening any borrow area, and request approval of the source under
the pay item involved. Test pits required by the Engineer to evaluate the acceptability and limits of
the source, shall be provided by the Contractor at the Contractor's own expense. Concurrent removal
of material for more than one pay item from a single source or pit shall be prohibited except with the
written permission of, and under such conditions and restrictions as may be imposed by the Engineer.
All borrow pits shall be stripped of sod, topsoil and vegetable matter well in advance of any working
face. The minimum distance by which stripping shall lead excavation for a given source shall be
established by the Engineer to suit local conditions. Where a borrow source is not under direct control
of the Contractor or where special conditions exist, the Engineer may waive any of the above
requirements and establish alternative provisions for the control and acceptability of borrow.
Ordinary borrow will be accepted for use where the material qualifies under the definition of
Suitable Material, §203-1.01H. Suitable Material. All borrow placed within the limits of
Embankment or the Subgrade Area shall be placed in conformance with §203-3.03B. Embankments
or §203-3.01G. Subgrade Area respectively, as appropriate, or where used for fill or backfill at
structures, culverts and pipes, in conformance with §203-3.06 Select Granular Fill and §203-3.17
Select Structural Fill.
G. Subgrade Area. Where a subgrade area is defined in an embankment by §203-1.01E. Subgrade
Area, the material placed shall conform to §203-2.01A. Subgrade Area Material, placed and
compacted in conformance with §203-3.03B. Embankments and §203-3.03C. Compaction. Where
25 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
longitudinal and transverse changes from cut to fill are encountered in the work, a subgrade transition
section shall be provided in conformance with Standard Sheet Earthwork Transition and Benching
Details. Where a subgrade area becomes defined by §203-1.01E. Subgrade Area in a cut section, the
materials placed and other details shall be as specified under §203-3.02C. Proof Rolling in Cut
Sections 3. Procedure, unless otherwise required by the contract documents. Prior to subbase course
placement, the surface on which the subbase is to be placed shall be thoroughly compacted to the
satisfaction of the Engineer.
1. Subgrade Surface Tolerance. After compaction, the subgrade surface shall not be above
design elevation at any location.
203-3.02 Unclassified Excavation and Disposal.
A. Rock Excavation. Presplitting is required where the design rock slope is 1 vertical on 1
horizontal or steeper and the vertical height of the exposed rock slope exceeds 5 ft. Ripping will not
be allowed within 10 ft. of a slope that requires presplitting. Test sections will be required at the
outset of presplit drilling and blasting operations for the evaluation of the presplit rock slopes by a
Departmental Engineering Geologist. The Contractor will be required to completely expose the
presplit rock face in the test section for evaluation prior to any further presplit drilling.
All rock slopes shall be thoroughly scaled and cleaned. For rock excavations involving multiple
lifts, scaling of upper lifts shall be completed prior to drilling and fragmenting of lower lifts. Scaled
rock slopes shall be stable and free from possible hazards of falling rocks or rock slides that endanger
public safety. If, after scaling, such conditions still exist, a determination of the cause will be made by
a Departmental Engineering Geologist and if it is determined that the conditions are the result of poor
quality work or improper methods employed by the Contractor, the Contractor shall provide approved
remedial treatment, at no expense to the State. Such treatment may include, but is not necessarily
limited to, laying back the slope, rock bolting, or shotcreting. In no case shall the subgrade be
trimmed prior to the completion of the scaling operation at any location.
1. Presplitting. Prior to drilling presplitting holes, the overburden shall be completely removed to
expose the rock surface along the presplitting line. The methods of collaring the holes to achieve
required inclination and alignment shall be approved by the Engineer.
The presplitting holes shall be a maximum of 4 in. in diameter, spaced not more than 3 ft.
center to center along the slope, and drilled at the designed slope inclination for a maximum slope
distance of 60 ft. When excavation operations are conducted in multiple lifts, the presplitting
holes for successive lifts may be offset a distance of not more than 3 ft. for a design slope of 1
vertical on 1 horizontal and not more than 1 ft. for slopes of steeper design; however, a
presplitting hole shall not be started inside the payment line. The Contractor shall control the
presplit drilling operations by using proper equipment and technique to achieve the design slope
and maximum bench between lifts. If presplitting is conducted in lifts, each lift shall be of
approximately equal depth. All presplitting holes shall be checked and cleared of obstructions
immediately prior to loading any holes in a round. All presplitting holes shall be loaded with a
continuous column charge manufactured especially for presplitting which contains not more than
0.35 lbs. of explosive per foot. The top of the charge shall be located not more than 3 ft. below
the top of rock. A bottom charge of not more than 3 lbs. of packaged explosive may be used;
however, no portion of any bottom charge shall be placed against a proposed finished slope. Each
presplitting hole shall be filled with No. 1A crushed stone stemming meeting the gradation
requirements of §703-02 Coarse Aggregate. The presplitting charges shall be fired with
detonating cord extending the full depth of each hole and attached to a trunk line at the surface.
Detonation of the trunk line shall be with blasting cap(s) and shall precede the detonation of
fragmentation charges within the section by a minimum of 25 milliseconds. Presplitting shall
26 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
extend for a minimum distance equal to the burden plus 3 ft. beyond the limits of fragmentation
blasting within the section.
2. Fragmentation Blasting. Fragmentation holes, or portions thereof, shall not be drilled closer
than 4 ft. to the proposed finished slope. Where presplitting is required, fragmentation holes
adjacent to the presplitting holes shall be drilled parallel to the presplitting holes for the full depth
of the production lift at a spacing not exceeding the spacing of the production pattern. Only
packaged explosives shall be used 10 ft. or less from a design slope which requires presplitting
regardless of the construction sequence.
Fragmentation charges shall be detonated by properly sequenced millisecond delay blasting
caps.
3. Explosive Loading Limits. In the absence of more stringent requirements, the maximum
quantity of explosives allowed per delay period shall be based on a maximum particle velocity of
2 in./s at the nearest structure to be protected. In the absence of seismic monitoring equipment,
the following explosive loading limits shall apply:
DISTANCE EQUAL TO OR LESS THAN 212 ft. FROM THE NEAREST STRUCTURE T
a. When the distance from the proposed blasting area to the nearest structure to be protected
is 6 ft. or less, no blasting shall be allowed.
b. When the distance between the blasting area and the nearest structure to be protected is
greater than 6 ft. and equal to or less than 15 ft., a maximum of ¼ lb. of explosives per delay
period (minimum of 25 milliseconds) blasting cap shall be allowed.
c. When the distance between the blasting area and the nearest structure to be protected is
greater than 15 ft. and equal to or less than 212 ft., a Scaled Distance of 30 ft. shall be utilized
to determine the maximum amount of explosive allowed per delay period (minimum of 25
milliseconds) blasting cap. The Scaled Distance Formula is as described below:
maxE
D = SD
where: SD = Scaled Distance
D = Distance from blasting area to nearest structure to be
protected in feet
or
2
2
max)(SD
D = E
where: maxE = Maximum pounds of explosive per delay period (minimum
of 25 milliseconds) blasting cap
DISTANCE GREATER THAN 212 ft. FROM THE NEAREST STRUCTURE
a. When the blaster elects to utilize more than 50 lbs. of explosive per delay period (minimum
of 25 milliseconds) blasting cap, a seismograph shall be employed to monitor the blasting
vibrations generated. The initial loading shall be computed using a Scaled Distance of 30 ft.
The resulting particle velocity measured by the seismograph shall be evaluated by a
27 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Department Engineering Geologist. The Geologist's evaluation shall be the basis for adjusting
the Scaled Distance.
No separate payment shall be made for this work. The cost shall be included in the
appropriate excavation item. The above requirements shall in no way relieve the Contractor of
liability for any damage incurred as a result of the blasting operations.
B. Disposal of Surplus Excavated Materials. Only unsuitable materials, or that portion of suitable
material excavated in excess of the quantity required to construct all embankments on the project,
shall be considered as surplus.
Where disposal of surplus materials cannot be accommodated within the right of way, the excess
shall become the Contractor's property for disposal. Surplus material disposed of within the right-of-
way shall be placed in accordance with §107-10 Managing Surplus Material And Waste.
C. Proof Rolling in Cut Sections. Immediately prior to final trimming of the subgrade surface and
placement of subbase materials in cut sections, all areas of the subgrade surface within roadway limits
shall be proof rolled according to the requirements of this subsection. This work, and any delays due
to this work, shall be considered incidental to the excavation item.
1. Purpose. In cut sections, the purpose of proof rolling is to determine the location and extent of
areas below the subgrade surface that require corrective undercutting and are not so specified in
the contract documents.
2. Equipment. The proof roller used in embankment sections, as specified in §203-3.03D. Proof
Rolling in Embankment Sections 1. Equipment, shall be employed for proof rolling in cut sections
except that the roller shall be loaded to achieve a single stress level in operation, using a gross
ballasted weight of 30 tons and all tires inflated to 40 psi.
3. Procedure. Two complete passes shall be applied over all elements of the area to be proof
rolled. Where any portion of the cut subgrade surface other than that which has been damaged by
the Contractor's operations fails to provide a satisfactory support for the proof rolling operation,
the Engineer may order corrective undercut and backfill work performed. Backfill of undercuts
shown in the contract documents or ordered by the Engineer shall be in conformance with
§203.3-13 Select Granular Subgrade. Where natural soil below this course will not support the
weight of the construction equipment, and when ordered by the Engineer, the course shall be
placed in one lift. No additional proof rolling shall follow corrective work.
4. Exceptions. Proof rolling of the subgrade surface in cut sections will not be required in any
area where the subgrade surface is in a rock cut, or where undercut and backfill has been
previously performed. The Engineer may order undercutting and backfill without proof rolling of
any cut where the need for corrective work, as determined by the Engineer, is obvious without
actual proof rolling. The Engineer may also delete proof rolling in any cut section where, based
upon a written evaluation by a Departmental Geotechnical Engineer, proof rolling would be
detrimental to the work.
203-3.03 Embankment In Place.
A. Embankment Foundation. After completion of the work required under Section 201 Clearing
and Grubbing, and Section 202 Removal of Structures and Obstructions, the embankment foundation
shall be prepared. Sod and topsoil shall be removed where the final pavement grade is 6 ft. or less
above the existing ground surface and in other areas designated in the contract documents or by the
28 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Engineer. Prior to embankment construction and subbase course placement, the surface on which the
embankment and/or subbase is to be placed shall be thoroughly compacted to the satisfaction of the
Engineer. Unsuitable materials other than sod and topsoil shall be removed to the depths shown in the
contract documents or as directed by the Engineer. Underwater areas shall be filled in accordance
with §203-3.04 Select Borrow or §203-3.05 Select Fill and paid for under its appropriate item.
Where embankments are to be constructed over ground that will not adequately support
embankment construction equipment, an initial layer of fill may be allowed to form a working
platform. The need, manner of construction, and thickness of such a layer shall be subject to approval
of the Engineer, and the layer will be permitted only where the lack of support is, as determined by
the Engineer, not due to deficient ditching, grading or drainage practices or where the embankment
could be constructed in the approved manner by the use of different equipment or procedures.
Thicknesses of up to 3 ft. may be permitted for such a layer. Concrete or asphalt slabs may be used at
the bottom of such a layer, provided they are placed horizontally.
In locations where embankments are to be constructed on hillsides or against existing
embankments with slopes steeper than 1 vertical on 3 horizontal, the slopes shall be benched.
Required benches shall be constructed as shown on the Standard Sheet Earthwork Transition and
Benching Details.
Where old pavement is encountered within 2 ft. of the top of the subbase course, it shall be
broken up or scarified.
B. Embankments. The embankment shall be constructed of suitable material as defined by §203-
1.01H. Suitable Material. Embankment material shall not be placed on frozen earth, nor shall frozen
soils be placed in any embankments. Embankment material shall be placed and spread in lifts (layers)
of uniform thickness, then uniformly compacted as specified under applicable portions of §203-
3.03C. Compaction. During embankment construction operations, earth moving equipment shall be
routed so as to prevent damage to any compacted lift. Damage to any compacted lift at any time
during the course of construction, such as rutting under the loads imposed by earth moving
equipment, shall be fully repaired by the Contractor at his/her own expense prior to placement of any
overlying materials. At the close of each day's work, the working surface shall be crowned, shaped
and rolled with smooth steel wheel or pneumatic tired rollers, for positive drainage.
Particles with a dimension in excess of ⅔ of the loose lift thickness are designated as oversized
particles. Oversized particles shall be removed prior to compaction of the lift and may be placed in
the Embankment Side Slope Area.
Pieces of concrete or asphalt may be used provided that the voids between the pieces are
completely filled, and the greatest dimension of any piece does not exceed ⅔ the loose lift thickness.
Exposed mesh or rebar shall not exceed 1 in. in length.
Embankments constructed using rock products or pieces of concrete shall be spread by bladed
equipment on each lift to minimize the formation of large voids as the work progresses. The top lift of
a rock or concrete fill shall be chinked.
When permitted by a note in the contract documents, stumps, logs, and other materials may be
placed in the Embankment Side Slope Area, provided that: 1) such matter is deposited and compacted
concurrent with the adjacent embankment, and; 2) any stumps or woody material are covered by not
less than 2 ft. of soil beneath the exposed side slope surface.
Glass shall not be placed in contact with synthetic liners, geogrids, geotextiles or other
geosynthetics.
C. CompactionT
1. General Requirements. It shall be the Contractor's responsibility to properly place and
compact all materials in the road section and other locations specified in the contract documents,
and to correct any deficiencies resulting from insufficient or improper compaction of such
29 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
materials throughout the contract period. The Contractor shall determine the type, size and weight
of compactor best suited to the work at hand, select and control the lift (layer) thickness, exert
control over the moisture content of the material, and other details necessary to obtain satisfactory
results. During the progression of the work, the Department will inspect the Contractor's
operations and will permit the work to continue where:
a. Lift thickness is controlled and does not exceed the maximum allowed according to the
equipment classifications in subparagraph 2. Compaction Equipment, of this subsection, and
the equipment meets all specified class criteria. Thinner lifts and lighter equipment than the
maximum allowed may be necessary for satisfactory results on some materials.
b. The compactive effort (number of passes and travel speed) is uniformly applied and not
less than that specified for the given equipment class and lift thickness. Higher efforts than
the minimum allowed may be necessary for satisfactory results on some materials.
c. The Engineer concludes from a visual observation that adequate compaction has been
attained, with the exception of backfill at structures, culverts, pipes, conduits, and direct
burial cables. However, the State reserves the right to perform density tests at any time. When
tests are performed, the results shall indicate that not less than 90% of Standard Proctor
Maximum Density is attained in any portion of an embankment, or 95% in a subgrade area,
or as specified for other items with a percent maximum density requirement.
d. Significant rutting under the action of the compactor is not observed on the final passes
on a lift.
Whenever the Contractor's operations do not conform to the above criteria, or requirements
contained in other subparagraphs of this subsection, the Engineer will prohibit placement of an
overlying lift until the Contractor takes effective corrective action.
As part of the Department’s Quality Assurance (QA) program, the Engineer or his
representative may verify the adequacy of the compaction at any time through QA testing. When
the Engineer determines that QA tests are necessary, the Contractor shall provide any assistance
requested to facilitate such tests. Such assistance shall include but will not be limited to
excavation and backfill of test pits and holes. This work shall be considered to be incidental
construction.
Damage to any compacted lift at any time during the course of construction such as rutting
under the loads imposed by earth moving equipment, shall be fully repaired by the Contractor at
his/her own expense prior to placement of any overlying materials.
2. Compaction Equipment. The selection of compaction equipment is the Contractor's
responsibility, but shall be subject to meeting the requirements of this subparagraph and approval
by the Engineer with respect to its provisions. All compaction equipment shall be marked by a
permanently attached manufacturer's identification plate designating the name of the
manufacturer, model number and serial number of the machine as minimum identification. This
plate shall be installed in a readily visible location. Compaction equipment lacking such an
original manufacturer's identification plate, or with altered or illegible plates, will not be
recognized as acceptable compaction equipment. Any equipment not principally manufactured
for soil compaction purposes and equipment which is not in proper working order in all respects
shall not be approved or used. The Engineer will also withhold approval of any compactor for
which the Contractor cannot furnish manufacturer's specifications covering data not obvious from
a visual inspection of the equipment and necessary to determine its classification.
30 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The term, “pass,” for any type of compactor, shall denote one direct vertical application of
compactor effort over all elemental areas of a lift surface. Terms in common parlance, such as
“coverage,” “trips,” etc., have no significance, equivalence, or application under these
specifications.

a. Pneumatic-Tired Compactors. This type of compactor shall be classified for use according
to the requirements of Table 203-1. For the lift thickness selected by the Contractor, the
minimum class and wheel load which will be allowed on that lift thickness, shall be as shown
in Figure 203-1.
31 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The minimum effort for all pneumatic compactors shall be 6 passes, at speeds up to 12
ft./sec on no more than the first 2 passes, and all subsequent passes at speeds of 6 ft./sec. or
less.
b. Smooth Drum Vibratory Compactors. This type of compactor is defined as a machine
which primarily develops its compactive effort from the vibrations created and is classified
for use according to the developed compactive force rating (CFR) per linear inch of drum
width.
The CFR is defined as follows:
CFR = Unsprung Drum Weight (lbs.) + Dynamic Force (lbs.)
Drum Width (in.)
32 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The unsprung drum weight is the static weight of the drum and appurtenances without
any reaction transmitted to the drum from the main chassis of the compactor. The dynamic
force produced is dependent on the frequency of vibration, and therefore, CFR ratings shall
be determined for the actual operating frequency of the compactor. Approval for vibratory
compactors shall be confined, however, to equipment operating at not less than 1100 vpm,
nor more than 1500 vpm, and those where the actual dynamic force at the actual operating
frequency is at least 2.5 times the unsprung drum weight.
Conversion of manufacturer's published ratings, at a given frequency, shall be made with
the following equation:
2
1
2
212
)(
)(
V
VF = F
where: 1F = Dynamic Force at Rated Frequency
2F = Dynamic Force at Operating Frequency
1V = Rated Frequency
2V = Operating Frequency
For the lift thickness selected by the Contractor, the minimum CFR rating and minimum
effort on such a lift, shall be as shown in Figures 203-2B&C, respectively. Non-Centrifugal
(Vertical force only) types of vibratory compactors shall be approved as above, less 175
lbs./in. before using Figures 203-2 B&C as a minimum number of passes at a single specified
speed. An equivalent effort, relating varying numbers of passes to other speeds is given by
the equation:
Speed X = (Specified Speed) (Min. Passes at Speed X)
(Specified Min. Passes)
The Contractor may choose to alter the specified minimum pass requirement, provided
that speed is adjusted to the value given by this equation and does not exceed 6 ft./sec.
33 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Where vibratory compactors are used on a project, the Contractor shall furnish for the
exclusive use of the Engineer, one vibrating reed tachometer per project, plus one additional
tachometer for each group of two vibratory compactors in excess of two per project.
Tachometers shall have a frequency range adequate to cover operating frequencies of all
vibratory compactors used on the project and shall have scale divisions of 50 vpm or less.
Tachometers may be placed on the ground surface near the compactor when making readings,
or with suitable damping materials interposed, placed directly on the compactor drum frame.
The dispensations permitted under this specification for vibratory compactors are
contingent upon proper operation of the equipment at all times during compaction operations.
In any instance where the Engineer encounters any problems with operators rolling without
34 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
vibration, for any reason, and immediate and effective corrective action is not taken by the
Contractor, the Engineer will halt the work until the problem is resolved. If continuing
problems of this nature occur, the Engineer may suspend all provisions of this subparagraph
and consider the vibratory compactors as smooth steel wheel rollers classified according to
their gross weight.
c. Sheepsfoot and Segmented Pad Foot Rollers. This type of compactor shall be defined as
a machine which is primarily designed to compact a lift from the bottom to the top.
The maximum loose layer thickness of the material to be compacted shall be equal to the
length of the feet plus 15%. The end area size and configuration of the feet shall be selected
by the Contractor to suit the characteristics of soil being compacted.
Where sheepsfoot and segmented pad foot rollers are used, with or without vibration, the
number of passes required for job control shall be determined by a jobsite test in which the
feet penetrate into the loose lifts and, with further passes, eventually and substantially “walk
out” of the layer. This job control shall then be established for that machine, lift thickness and
material, provided that adequate moisture control is continuously maintained per §203-3.03C.
Compaction 3. Moisture Control. Sheepsfoot and segmented pad foot rollers shall be
operated at speeds not exceeding 6 ft./sec., when towed and 15 ft./sec. when self-propelled.
d. Smooth Steel Wheel Rollers. Smooth steel wheel rollers shall be considered as primary
compactors on layers whose maximum thickness, after compaction, is 8 in. When so used, the
roller shall have a nominal gross weight of not less than 10 tons, exert a minimum force of
not less than 300 lbs/in. of width on the compression roll faces, and a minimum of 8 passes
shall be applied over each lift with the roller operating at a speed not exceeding 6 ft./sec.
When the Contractor employs smooth steel wheel rollers exclusively for surface
compaction, leveling or finishing operations on lifts previously compacted by other types of
primary compactors, the above restrictions shall not apply.
This section applies to non-vibratory rollers or vibratory rollers operated in the static
mode only.
e. Other Type of Compactors. Compactor types other than those classified above, may be
employed by the Contractor, subject to approval by the Engineer of the proposed minimum
applied effort (minimum number of passes and travel speed) and maximum lift thickness.
Such approval by the Engineer will be based upon the results of appropriate on-site field
tests.
f. Compaction Equipment for Confined Areas. In areas inaccessible to conventional
compactors, or where maneuvering space is limited, impactor rammers, plate or small drum
vibrators, or pneumatic buttonhead compaction equipment may be used with layer thickness
not exceeding 6 in. before compaction. Hand tampers shall not be permitted. The Engineer
may approve or reject any of the above described mechanical devices based upon the results
of appropriate on-site field tests.
3. Moisture Control. All fill or backfill material to be compacted, shall be at a moisture content
for adequate compaction of that material using the compactor selected by the Contractor to
perform the work. The Contractor shall be responsible for determining the appropriate moisture
content, and for controlling it within the proper limits as the work is progressed. When water
must be added to a material, it may be added on the lift or in the excavation or borrow pit. Water
added on the lift, however, shall be applied by use of an approved pressure distributor.
Distributors must be approved and documented by the Engineer. Documentation by the Engineer
shall be adequate evidence of approval. Water added shall be thoroughly incorporated into the
35 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
soil, and the soil shall be manipulated to attain uniform moisture distribution. When the moisture
content of a lift about to be compacted exceeds the required amount, compaction shall be deferred
until the layer has dried back to the required amount. Natural drying may be accelerated by
blending in a dry material or manipulation alone, to increase the rate of evaporation. Increased
loose lift thickness caused by blending in a dry material, however, may necessitate a change in
compaction equipment and/or methods to meet the minimum provisions of subparagraph 2.
Compaction Equipment of this subsection.
D. Proof Rolling in Embankment Sections. Immediately prior to final trimming of the subgrade
surface and placement of subbase materials in embankment sections, all areas of the subgrade surface
within roadway limits shall be proof rolled according to the requirements of this subsection. This
work, and any delays due to this work, shall be considered incidental to the embankment item.
1. Equipment. The proof roller shall consist of a chariot type rigid steel frame with a box body
suitable for ballast loading up to 50 tons gross weight, and mounted on four pneumatic tired
wheels acting in a single line across the width of the roller on its transverse load center line. The
wheels shall be equipped with 18.00 x 24 or 18.00 x 25, 24 ply tires, and shall be suspended on
articulated axles such that all wheels carry approximately equal loads when operating over
uneven surfaces.
36 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
2. Determination of Roller Stress. Initially, the gross ballasted weight and tire inflation pressure
of the proof roller shall be adjusted to the highest stress level shown in Figure 203-3 based on:
a. The general description of the subgrade soils.
b. The estimation of the relative subgrade support within the subgrade soil description
range.
The initial roller stress for embankments constructed of rock shall be the maximum level
listed in Figure 203-3 (50 Gross Tons, 130 Tire psi).
The roller shall be operated briefly to establish the acceptability of the initial stress level.
Proof rolling of the embankment shall be performed at the next lower stress level whenever
operation of the roller at a higher stress level is accompanied by consistent lateral displacement of
soil out of the wheel paths.
3. Procedure. After an acceptable stress level is established, two complete passes of the roller
shall be applied over all elements of the area to be proof rolled. Any deficiencies disclosed during
the proof rolling operation shall be corrected. Subsidence depressions shall be filled with material
similar to the subgrade soil and then compacted in a normal manner. After compaction, these
areas shall be proof rolled again. Corrective work shall be judged complete and accepted by the
Engineer when all elements of the subgrade surface over a given embankment show a satisfactory
uniform response to the proof roller.
4. Exceptions. Proof rolling of the subgrade surface in embankment sections will not be required
in any area where:
a. Due to restrictions in available access and/or maneuvering space, use of the proof roller
may damage adjacent work;
b. The proof roller will approach a culvert, pipe or other conduit closer than 5 ft. in any
direction.
203-3.04 Select Borrow. The management of a select borrow source and the acceptability of all select
borrow material shall be in conformance with §203-3.01F. Borrow.

SECTION 204 - FLOWABLE FILL
204-1 DESCRIPTION. The work shall consist of mixing and placing flowable fill at the locations
shown in the contract documents.
204-1.01. Controlled Low Strength Material. Controlled Low Strength Material (CLSM) is an
acceptable alternative to compacted soil backfill in confined spaces. CLSM consists of cement, water and,
at the Contractor’s option, fly ash, aggregate or chemical admixtures in any proportions such that the final
product meets the strength and flow consistency requirements included in the specification. The mix is
proportioned to be self leveling and does not require compaction. It is much lower in strength than
concrete, making future excavation possible.
204-1.02. Lightweight Concrete Fill. Lightweight Concrete Fill is an engineered geotechnical material
with a unique strength / density relationship which can be used to reduce loads on soft foundation soils,
buried structures, or against retaining walls. Lightweight Concrete Fill consists of a Portland cement
matrix containing uniformly distributed, non-interconnected air voids introduced by a foaming agent. The
flowability and cementitious properties provide a product that is self leveling and does not require
compaction.
204-2 MATERIALS.
204-2.01 Controlled Low Strength Material. Provide backfill material meeting the requirements for
CLSM as stated in §733-01 Flowable Fill.
204-2.02 Lightweight Concrete Fill. Provide backfill material meeting the requirements for
Lightweight Concrete Fill as stated in §733-01 Flowable Fill.
204-3 CONSTRUCTION DETAILS.
204-3.01 Controlled Low Strength Material.
A. CLSM Submittal. Submit to the Engineer (1) a mix design, with certified test results supplied by
a qualified independent testing laboratory for the CLSM verifying the unconfined compressive
strength meets the requirements of the specification, and (2) the methods of installation to be
employed. Include in the CLSM placement sequence, a procedure to account for subsidence during
the settling and curing process.
B. CLSM Production. Mix the materials at a stationary mixing plant which is either a continuous or
a batch type plant. A batch is defined as the amount of material that can be mixed at one time. Design
the mix of materials to accurate proportions, either by volume or by weight, so that when the
materials are incorporated in the mix a thorough and uniform mix will result.
If the CLSM can be placed within 30 minutes of the end of mixing, then open haul units may be
used for transport. If it cannot be placed within 30 minutes after the end of mixing, it must be
transported by a rotating drum unit capable of 2-6 rpm.
43 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
For work involving quantities of CLSM less than 2.5 yd3, the Contractor may use a small portable
mixer. Provide a mixer capable of mixing CLSM that has the specified unconfined compressive
strength and flow consistency. Mix all components so as to produce a uniform product.
C. CLSM Placement - General. Do not place CLSM that is frozen, or place CLSM on frozen
ground. Do not expose CLSM to freezing temperatures until after it has gained its requisite strength,
abiding by the Provisions for Curing in Cold Weather in Section 555 Structural Concrete.
If the CLSM is to be placed via pumps, the placement sequence shall be such that the equipment
is able to access the entire volume to be filled without separating the mixture.
Keep CLSM encapsulated with soil or protected by other means so as to prevent erosion and
environmental degradation.
D. CLSM Placement – at Structures, Culverts, Pipes, Conduits and Direct Burial Cables. Place
the CLSM in accordance with the installation details shown on the Standard Sheet.
When placing CLSM for pipe backfill, discharge the material onto the top and at the center of the
pipe.
Do not place CLSM in contact with aluminum pipe, including connections, fixtures, etc., unless
the aluminum has been thoroughly coated with Zinc Chromate Primer, §708-04 Zinc Chromate
Primer, or an equivalent alternative as approved by the Materials Bureau.
Do not place CLSM containing fly ash in direct contact with cast iron or ductile iron pipes,
fittings or appurtenances.
In situations where CLSM is used as backfill around pipe, take precautions to counteract the
pipe’s buoyancy.
E. CLSM – QA Testing. The Department maintains a Quality Assurance (QA) program for CLSM.
The Department will sample and test specimens of the CLSM during placement to compare its
properties to the specification requirements and verifying the spread diameter and unconfined
compressive strength of the in-place material. The QA program provides oversight of the Contractors
Quality Control (QC) process, to reveal changes which may occur in the approved mix design.
Several scenarios may develop as a result of the QA testing.
1. The properties are shown to meet the requirements of the specification for the type(s)
identified in the contract documents. No action will be taken.
2. The properties are shown to be outside the requirements of the specification for the type(s)
identified in the contract documents.
a. If the results are within an acceptable margin as determined by the Department through
an independent analysis of the site specific conditions, the material may remain in-place
contingent upon an agreed credit. If a credit cannot be agreed upon, the scenario reverts
to 2.b.
b. If the results are not within an acceptable margin as determined by the Department
through an independent analysis of the site specific conditions, the entire lift (and all
overlying lifts) of material will be removed and replaced at the Contractor's expense.

B. Lightweight Concrete Fill Production. Generate foam in accordance with the manufacturer’s
recommendations for inclusion into the mix.
Mix the materials at a stationary mixing plant which is either a continuous or a batch type plant.
A batch is defined as the amount of material that can be mixed at one time. Design the mix of
materials to accurate proportions, either by volume or by weight, so that when the materials are
incorporated in the mix, a thorough and uniform mix will result.
Locate equipment such that the mixed product is capable of being pumped into place properly.
C. Lightweight Concrete Fill - Placement. A representative of the supplier of the foaming agent
shall be on site during the initial placement and at such times as requested by the Engineer to advise
the Contractor on his operation. The lightweight concrete fill shall be placed in lifts not to exceed 24
in. unless otherwise approved by the Engineer. Subsequent lifts shall be placed only after a minimum
12 hour waiting period has been observed.
At the end of each pour, exposed surfaces shall be roughened with a stiff broom or scored with a
tool. The Lightweight Concrete Fill shall be placed on supporting surfaces which have been cleaned
of loose debris, sand, dust, or other foreign materials to the satisfaction of the Engineer.
Do not place Lightweight Concrete Fill that is frozen, or place Lightweight Concrete Fill on
frozen ground. Do not expose Lightweight Concrete Fill to freezing temperatures until after it has
gained its requisite strength, abiding by the Provisions for Curing in Cold Weather in Section 555
Structural Concrete.
D. Lightweight Concrete Fill – QA Testing. The Department maintains a Quality Assurance (QA)
program for Lightweight Concrete Fill. The Department will sample and test specimens of the
Lightweight Concrete Fill material during placement to compare its properties to the specification
requirements and verifying the wet cast density and unconfined compressive strength of the in-place
material. The QA program provides oversight of the Contractors Quality Control (QC) process, to

• At the end of each work day, contaminated soil stockpiles shall be completely covered with a
minimum of 10-mil or 2 layers of 6-mil polyethylene sheeting, or an equivalent material. All
seams shall be overlapped and sealed to prevent the leaching of contaminants.
• Stockpile covers shall be weighted or secured by appropriate means to prevent tearing or
removal by weather conditions.
• Stockpiles shall be labeled, signed, fenced or otherwise secured (as needed) at the end of each
work day.
3. Maintenance.
• Stockpile covers, site grading, signing and security measures shall be properly maintained for
the duration of storage.
• Damaged covers and other protections shall be repaired or replaced by the Contractor within
24 hours after notification. If this work is not satisfactorily completed within 24 hours, no
further stockpiling shall be allowed until such work is completed.
B. Trucks or Roll-off Containers. The Contractor shall prepare and maintain trucks and roll-off
containers as follows:
• The interior of truck-beds and roll-off containers shall be lined with 10-mil or 2 layers of 6-
mil polyethylene sheeting, or an equivalent material. All seams shall be overlapped and
sealed to prevent the leaching of contaminants.
• At the end of each work day, trucks and roll-off containers storing soil shall be completely
covered with waterproof tarpaulins. Tarpaulins shall be placed over the top of the truck bed
or container (rather than over the soil inside) and shall extend over the sides to prevent water
accumulation and the evaporation of contaminants.
• Tarpaulins shall be weighted or secured by appropriate means to prevent tearing or removal
by climatic conditions.
• Trucks and roll-off containers shall be labeled, signed, fenced or otherwise secured (as
needed) at the end of each work day.
• Trucks, roll-off containers and tarpaulins shall be properly maintained for the duration of soil
storage.
• Damaged tarpaulins and protections shall be repaired or replaced by the Contractor within 24
hours after notification. If this work is not satisfactorily completed within 24 hours, no further
soil storage shall be allowed until such work is completed.
• Trucks and roll-off containers storing contaminated soil shall be located as described in
CMHP.
205-3.03 Field Organic Vapor Monitoring. The Contractor shall hire an independent firm to perform
field organic vapor monitoring in accordance with the accepted FOVMP. The individual conducting the
monitoring, hereafter referred to as the Field Monitor, shall be experienced and thoroughly trained in
sampling protocols, organic vapor monitoring procedures, and equipment calibration procedures. The
Field Monitor shall screen potentially contaminated soil during excavation using field vapor monitoring
equipment (PID/FID) and visual observations. Based on the screening results, the Field Monitor shall
direct the Contractor on the proper segregation of the material.
Field organic vapor monitoring shall be conducted when working in the contaminated soil areas
identified in the contract documents, or whenever unusual or suspicious soil conditions based on visual or
odor evidence are encountered during excavation. The Contractor or Field Monitor shall notify the
Engineer immediately if soil is discovered that appears to contain unknown contaminants or soil that
varies significantly from the type of contamination identified in the contract documents. (For health and
safety reasons, personnel shall not evaluate odor by placing soil directly to the nose or by inhaling vapors
from grab or bag samples).
51 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The Field Monitor shall calibrate the PID/FID on a daily basis prior to starting field work and shall
determine a background measurement. Excavated soil shall be tested with the PID/FID at intervals that
will ensure the soil is being properly assessed for contamination. The PID/FID will be used to take head
space readings from bag samples with the soil temperature at least 50OF. The Field Monitor shall
maintain detailed and legible field notes indicating work locations, nature of work being performed,
PID/FID head space readings, time of readings, pertinent measurements, visual and odor observations,
quantities of both contaminated and non-contaminated soils excavated at each location, storage/stockpile
locations, work hours, weather conditions, and any unusual conditions encountered. The Contractor shall
provide the Engineer with a copy of all field notes within 5 work days from their recording.
The segregation threshold established below (25ppm) is based on gasoline being the predominant
contaminant. If a different contaminant(s) is present or suspected, a different segregation threshold may
need to be established. Alternative segregation thresholds may be designated in the contract documents.
PID/FIDs detect and measure gas concentrations (specifically volatile organic compounds); they do
not quantify or identify the contaminants in the soil. Therefore, PID/FID readings can not determine
specific contaminant concentrations within the soil.
Segregate soil as follows:
A. Non-Contaminated Soil. Soil with PID/FID head space readings less than 25 ppm and exhibiting
no other evidence of contamination (visual or olfactory evidence) shall be considered non-
contaminated. Unless further analysis is performed for confirmation of the non-contaminated soil,
this soil will be considered uncontaminated.
B. Contaminated Soil. Soil with PID/FID head space readings equal to or greater than 25 ppm
and/or soil exhibiting other evidence of contamination (visual or olfactory evidence) shall be
considered contaminated. This soil shall be segregated from non-contaminated soil and placed in
stockpiles or containers. If sampling and analysis provisions are included for the segregated soil, the
results of laboratory analysis will be used to determine its regulatory classification. If feasible, soil
with significantly higher PID/FID head space readings and soil exhibiting unusual visual or odor
characteristics shall be segregated from other contaminated soil.
205-3.04 Sampling and Analysis. The Contractor shall have an accepted Sampling Plan prior to
commencing work within potentially contaminated areas. Sampling shall be conducted by individuals
thoroughly trained in sampling protocols, handling and chain of custody procedures, and laboratory
requirements. Accepted sampling practices shall be used to obtain representative composite sample(s)
and/or grab sample(s) as required for the specific analyses to be completed. Representative samples shall
be collected from stored soil as soon as possible after excavation. Soil shall be taken from a depth greater
than one foot within the stockpile. Each composite sample shall include a minimum of four sample
points. Grab samples shall be collected in a manner so as to best characterize the extent of contamination
of the soil in question and best characterize the extent of contamination of the pile. If any soil areas are
present with field indications of contamination discretely different than the other areas (i.e., significantly
elevated PID/FID readings, staining, etc.), the area may require a separate sample and the Engineer shall
be alerted to approve additional sample and analysis. Analyses shall be completed at a NYSDOH ELAP
accredited laboratory that is certified to perform the required tests. Analyses shall be completed within 10
work days of sample collection. The Contractor shall provide the Engineer with a copy of all reports
within 2 work days of their receipt from the laboratory. Soil shall not be added to any stockpile, truck or roll-off container after its contents have been
sampled. If soil is added after sampling, or sampled soil is otherwise tampered with, the Contractor shall
re-sample the soil at no additional cost to the State.
Conduct specified analyses as follows:
52 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
A. Petroleum Contamination Parameter Analysis. Samples shall be analyzed for petroleum
contamination constituents (total constituent analysis) in accordance with CP – 51/Soil Cleanup
Guidance, Gasoline and Fuel oil, Tables 2 and 3 using USEPA Method 8260 for volatile organics and
methyl t-butyl ether (MTBE) and USEPA Method 8270 for base/neutrals.
B. Hazardous Waste RCRA Toxicity Characteristic Analysis. Samples shall be analyzed for
Hazardous Waste RCRA Toxicity Characteristics Leaching Procedure (TCLP) constituents. Analysis
shall be for full TCLP constituents on the sample extract as prepared by USEPA Method 1311.
C. Ignitability of Solids Analysis. Samples shall be analyzed for ignitability by USEPA Method
1030.
D. pH of Soil and Waste. Samples shall be analyzed for pH measurement by USEPA Method 9045.
E. Polychlorinated Biphenyls (PCB) Analysis. Samples shall be analyzed for PCBs by USEPA
Method 8082.
F. Total Petroleum Hydrocarbons (TPH) Analysis. Samples shall be analyzed for petroleum
hydrocarbons, USEPA Method 8015, gasoline range organics (GROs) and/or diesel range organics
(DROs).
205-3.05 Transportation and Disposal. The Contractor shall have an accepted Disposal Plan prior to
the transportation and disposal of contaminated soil. Contaminated soil shall not be transported until all
sampling and analysis, as required by the Department or by the Disposal facility, have been performed
and laboratory reports have been provided and accepted by the Department.
A. Transportation Off Site.
1. For the duration of transportation, roll-off containers and truck beds shall be completely
covered with secured waterproof tarpaulins to prevent water infiltration, evaporation of
contaminants and spillage of contaminated soil.

209-3 CONSTRUCTION DETAILS.
209-3.01 General. In the event of conflict between these requirements and pollution control laws, rules,
regulations or permit conditions by other federal or state agencies, the more restrictive shall apply.
Soil erosion and sediment control shall be performed consistent with §107-12 Water Quality Protection
and included as part of the construction schedule submitted by the Contractor in accordance with §108-01
Start and Progress of Work.
To the extent practicable, this work shall be coordinated with other items of work specified elsewhere
in the contract documents. The intent is to assure effective and continuous erosion and sediment control
throughout the construction phase and post construction to reduce the impacts of soil loss on receiving
waters and adjacent properties.
Sediment controls shall be installed prior to performing grubbing, excavation, and borrow or fill
operations, except for those actions necessary to install the sediment controls. The Contractor shall limit
the area of clearing and grubbing, excavation, borrow and embankment operations in progress
commensurate with their capability to minimize erosion and sediment transport and keep the finish grading,
mulching, seeding and other temporary and/or permanent control measures current in accordance with the
approved schedule. The Engineer may determine that a potential for erosion or sediment transport exists
and direct the Contractor to install temporary erosion controls earlier. When permanent soil erosion and
sediment control measures cannot be installed due to seasonal or other limitations, temporary soil erosion
and sediment control measures shall be installed. Prior to removing or disturbing any erosion or sediment
control measure that may be required to be reestablished due to continual grading operations, the Contractor
shall verify the proposed progression of operations and the reestablishment of control measures with the
Engineer to ensure the continuity of erosion and sediment control. Sediment control measures shall not be
removed without the Engineer’s approval.
A. Inspection and Maintenance. Soil erosion and sediment control measures shall be inspected and
maintained by the Contractor for the duration of the contract, including winter shutdown, etc. Inspection
and maintenance shall continue until after the permanent stabilization measures are established and the
temporary control measures are removed. The remaining disturbed area shall be permanently stabilized
in accordance with the contract documents.
All temporary controls shall be inspected by the Contractor at least every seven calendar days and
after each runoff event to determine if the practice is functioning as intended. All inspections shall be
completed within one calendar day.
Within 1 work day from completion of the inspection, the Contractor shall:
• Repair or rebuild the practice to function as originally intended.
• Remove sediment deposition which reaches one half the height of the practice.
All sediment removed during maintenance of the practice shall be considered unsuitable material
and disposed of in accordance with §203-3.01E Unsuitable Material. Material shall be disposed of
away from sensitive resources including wetlands, water courses or other bodies of water.
Where erosion control materials have been used on final grades that have been permanently seeded,
the Contractor shall care for the areas until acceptance of the Contract or acceptance of the turf,
whichever is later. Where necessary, such care may include, but is not limited to providing warning
signs or barricades for protection against traffic. In addition to routine maintenance, any surface that
has settled, become gullied, or otherwise damaged due to the Contractor’s operations shall be repaired
at no additional expense to the state to reestablish the grade and soil conditions that existed prior to
placing erosion control materials.

shall be spread uniformly in a continuous blanket at an approximate rate of 2 tons per acre by hand, or by
mechanical spreaders or blowers. Mulch and seed shall not be placed simultaneously, except in the case of
hydroseeding. The Contractor shall secure straw mulch to the soil surface by crimping or applying a soil
stabilizer immediately after mulching, then water the seeded area. The application of water shall not result
in damage to the seeded area including the redistribution of seeds (congregating seeds as a result of ponding
or pooling water) or soil erosion (rilling).

with additional coarse aggregate material.
209-3.10 Turbidity Curtain-Temporary.
A. Systems Requirements.
1. For sites not subject to tidal or heavy wave action, the curtain height shall provide sufficient
slack to allow the top of the curtain to rise to the maximum expected high-water level (including
waves), while the bottom maintains continuous contact with the bottom of the water body. The
bottom edge of the curtain shall have a weight system capable of holding the bottom of the curtain
down and conforming to the water body, so as to prohibit escape of turbid water under the curtain.
2. For sites subject to tidal or heavy wave action, the curtain height shall provide sufficient slack to
allow the top of the curtain to rise to the maximum expected high-water level (including waves),
while the bottom remains 24 inches above the bottom. The weight system shall hold the lower edge
71 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
of the curtain in place so as to allow 24 inches of clearance above the bottom at mean low water,
so that the curtain does not stir up sediment by repeatedly striking the bottom.
3. If constructed in panels, panels shall be connected in such a manner as to prevent suspended
particles passing through joints. Load lines shall be connected so as to develop the full strength of
the line across the joint.
4. Flotation material shall be arranged so as to be flexible and to provide continuous support.
5. The flotation and curtain top shall be such as to provide a minimum of 4 inches of freeboard
along the entire length of the curtain, to prohibit escape of turbid water over the top.

1. The turbidity curtain shall be installed as shown in the contract documents in accordance with
the Manufacturer’s instructions. It shall be placed as close to the site of disturbance as possible
without interfering with construction activity.
2. Turbidity curtain shall be installed and maintained in a manner that precludes passage of
equipment, other than hand-held equipment or boats, to the water body outside the protected area.
3. The fully assembled turbidity curtain shall be prepared for installation by being furled and tied
at intervals of 5 feet for the length of the curtain. It shall be placed and secured in the furled
condition, then released to allow the bottom edge to sink.
4. At sites subject to tidal or heavy wave action, adjustment lines may be used to achieve the
required height of the curtain.
5. At sites not subject to tidal or heavy wave action, excess curtain material shall lay on the bottom,
away from construction activity.
6. Turbidity curtain shall be placed as nearly as possible parallel to current flow. It shall not be
deployed across a flowing water course.
7. The ends of the installation shall be anchored securely well up the bank. Intermediate anchors of
a type and number sufficient to hold the curtain in place under expected conditions shall be placed,
and firmly fastened to the top of the curtain assembly. Maximum spacing between anchorage
points shall not exceed 100 feet.
8. In situations with flow velocities that exceed 5 feet per second, use a redirection barrier. The
redirection barrier shall be installed prior to installation of the turbidity curtain wherever possible,
and care should be exercised in order to minimize disturbance of the bottom of the water body
during installation of the redirection barrier.
C. Inspection and Maintenance
1. The turbidity curtain shall be inspected daily, with additional monitoring of performance during
storms or significant flow events.
2. Any visible plume of turbid water passing beyond the curtain from the enclosed construction
area shall constitute inadequate performance of the turbidity curtain. The Contractor shall
72 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
immediately modify, adjust, or repair any portion of the turbidity curtain to correct inadequate
performance.
3. The turbidity curtain shall remain in place until the protected construction activities have ceased
and there is no visible contrast between the water being contained and the water body being
protected.
D. Removal.
1. The turbidity curtain shall be removed in such a way so as to minimize release of sediment.
2. Sediment behind the curtain may be removed before removal of the curtain, if directed by the
Engineer. If so, any resulting turbidity must be allowed to settle before removal proceeds.

SECTION 211 - INTERNALLY STABILIZED CUT STRUCTURES
211-1 DESCRIPTION. This work shall consist of designing, furnishing, installing, and testing an
internally stabilized cut structure at the location(s) and to the elevation(s) shown in the contract
documents.
211-1.01 Soil Nail Wall System. A Soil Nail Wall System is comprised of cement-grouted steel nail
tendons, a drainage network and a facing system to internally stabilize a cut and/or underpin a structure.
A. Soil Nail Wall System (SNWS) Definitions.
1. Soil Nail. A passive reinforcing element which develops its reinforcing action through nail
tendon/ground interaction. A soil nail includes the SNWS nail tendon, the SNWS nail head,
grout, coatings, sheathing, couplers and encapsulation if used.
2. SNWS Nail Tendon. A steel bar installed into a slope to reinforce and strengthen the existing
ground.
3. SNWS Nail Head. The nail head consists of the bearing plate and headed-stud. The bearing
plate distributes forces at the nail end to the wall and ground behind the facing. The headed-
stud provides anchorage of the nail head into the permanent facing.
4. Grout. Grout is used primarily as a transfer mechanism for stresses from the wall to the
ground. The grout also provides a level of corrosion protection.
5. Centralizers. Centralizers are devices, typically PVC, installed at various locations along the
length of the nail tendon to center the bar in the excavated hole to ensure a minimum
thickness of grout cover.
6. Corrosion Protection Elements. These are physical and/or chemical coatings or systems
used to inhibit corrosion. Nail tendons may have a fusion-bonded epoxy coating applied. For
maximum protection, encapsulation consists of surrounding the nail tendon with a HDPE or
PVC corrugated protective sheathing and filling the internal annulus with grout. Subsequent
80 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
to installing the encapsulated nail into the excavated hole, the outer annulus is also filled with
grout.
7. Temporary Wall Facing. This consists of reinforced shotcrete installed to provide a
connection between nail tendons, support the exposed soil within the nail tendon grid and
provide protection against erosion and sloughing of the soil at the excavation face.
8. Wall Drainage Network. A system of drainage devices installed to prevent water pressure
from developing behind the wall face. The system typically consists of a series of vertical
geocomposite drainage strips and weep holes. Additional devices include footing drains and
horizontal drains.
9. GUTS. The Guaranteed Ultimate Tensile Strength of the tendon.
211-1.02 Grouted Tieback System. A Grouted Tieback System is comprised of cement-grouted steel
tendons installed to internally stabilize and supplement the resisting force of an external support system
retaining a cut and/or underpinning a structure.
A. Grouted Tieback System (GTS) Definitions.
1. Grouted Tieback. An active reinforcing element which transfers tensile loads from a
structure to soil or rock. A grouted tieback includes all prestressing steel (tendon), the
anchorage, grout, coatings, sheathing, couplers and encapsulation if used.
2. GTS Tendon. The steel used to transfer load from the anchorage to soil or rock.
3. Anchorage. That portion of the tieback, including bearing plate, nuts and wedges that is used
to transfer load from the structure to a tendon.
4. Bond Length (Fixed Length). That portion of the tieback which is bonded to the soil or rock
and transfers the tensile force from the tendon to the soil or rock.
5. Tendon Bond Length. The length of the tendon which is bonded to the grout. This is
usually, but not necessarily, the same as the Bond Length.
6. Stressing Length (Free Length). That portion of the tendon which is not bonded to grout.
7. Sheath. That portion of the tieback which encases the tendon in the stressing length only.
8. Encapsulation. That portion of the tieback which encases or encapsulates the entire length of
the tieback, including the sheath, to provide an additional barrier to corrosion.
9. Pressure Grouting. Grouting with a pressure greater than 50 psi.
10. Alignment Load. That load necessary to maintain position of the stressing and testing
equipment.
11. Total Movement. The total elongation of the tieback under load, measured at the anchor
head.
12. Residual Movement. The permanent set of the tieback resulting from stressing and releasing
the tieback.
13. Trumpet. A steel pipe or tube, integrally attached to the bearing plate that surrounds the
tendon in the vicinity of the structure.
14. Creep Rate. The magnitude of total movement measured during a load hold per log cycle of
time.
15. Centralizer. A device used to center the bond length of the tieback in the hole to assure
minimum grout cover over the tieback.
16. Spacer. A device used in strand tendons to separate each strand in the bond length to permit
the grout to bond with each strand.
17. GUTS. The Guaranteed Ultimate Tensile Strength of the tendon.

control pipes or conduits from the site.
C. SNWS Nail Installation. Excavation shall be conducted in accordance with the applicable
requirements of Section 206, Trench, Culvert and Structure Excavation, and the details specified in
the contract documents. Excavate using procedures that prevent over-excavation, ground loss,
swelling, air slaking or loosening, loss of support for completed portions of the wall, loss of soil
moisture at the face, or ground freezing.
Drill holes for the soil nail installation using core drilling, rotary drilling, or auger drilling.
Percussion drilling is prohibited unless approval for its use is granted by the DCETS. Install casing as
required to maintain a clean and open hole. Utilize a drill bit with a diameter not smaller than the
specified hole diameter minus ⅛ in. Extend the hole a minimum of 2 ft. beyond the nail length. Drill
the holes to the inclination specified on the approved Working Drawings within a 3° tolerance.
Provide centralizers at a maximum of 10 ft. center-to-center spacing throughout the length of the
nail to position the bar within 1 in. of the center of the hole and to provide a minimum 1 in. grout
cover over bare or epoxy-coated bars or ½ in. grout cover over the encapsulation of an encapsulated
nail. Size the centralizers to allow insertion of a tremie pipe to the bottom of the drillhole and to
allow grout to freely flow up the drillhole. Provide a centralizer within 2 ft. of the top and bottom of
the nail. Sag of the nail shall be taken into account when selecting centralizer diameter and spacing.
Insert the nail in the casing or hole after the hole is drilled to the final depth. Locate the nail
within a 6 in. tolerance, in any direction. Location tolerances are applicable to only one nail and not
accumulative over large wall areas.
Repair encapsulated nails that are damaged or defective in accordance with the manufacturer’s
recommendations or remove them from the site.
Provide a colloidal mixer and grouting equipment capable of continuous mixing and producing
grout free of lumps equivalent to the strength and consistency of the approved mix design created by
the independent testing laboratory. Equip the grout pump with a grout pressure gage capable of
measuring at least twice but not more than three times the intended grout pressure. Size the grouting
equipment to enable the entire nail to be grouted in one continuous operation. Place grout within 60
85 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
minutes after mixing or within the time recommended by the admixture manufacturer, if admixtures
are used. Grout not placed in the allowed time limit will be rejected.
Perform the grouting operation after the nail is inserted. Grout each drillhole within 2 hours of
completion of drilling. To prevent air voids, fill the hole with grout progressively from the bottom to
the top. Completely fill the drillhole in one continuous operation. Cold joints in the grout column are
not allowed except at the top of the test-bond length of proof-tested production nails.
Maintain sufficient grout level within the casing to offset the external groundwater/soil pressure
and prevent hole caving during casing removal for drillholes advanced by either cased or auger
methods. Maintain grout head or grout pressures sufficient to ensure that the drillhole will be
completely filled with grout and to prevent unstable soil or groundwater from contaminating or
diluting the grout. Control grout pressures to prevent excessive ground heave or fracturing.
Remove the grout and nail if grouting is suspended for more than 30 minutes or does not satisfy
the requirements of this specification or the approved Working Drawings, and replace with fresh
grout and undamaged nail bar at no additional cost.
Test nails as specified in §211-3.01 E SNWS Testing.
D. SNWS Facing Elements. Install and secure all elements of the wall drainage network as shown
on the approved Working Drawings. Secure the geocomposite drainage strips tightly to the
excavation face to prevent shotcrete from contaminating the ground side of the geotextile.
Geocomposite drainage strips shall be continuous. Splices to the geocomposite drainage strips shall
be made with a 1 ft. minimum overlap such that the flow of water is not impeded. Install all elements
of the drainage network, exclusive of the wall footing drains, prior to shotcreting. Clean the face of
the excavation, and other surfaces to be shotcreted, of loose material, mud, rebound, overspray, or
other foreign matter that could prevent or reduce shotcrete bond. Remove material that loosens as
shotcrete is applied.
Place shotcrete in accordance with the requirements of Section 583-3.03 Placement.
Provide shotcrete equipment capable of delivering the premixed material accurately, uniformly
and continuously through the delivery hose. Control shotcrete application thickness, nozzle technique,
air pressure, and rate of shotcrete placement to prevent sagging or sloughing of freshly applied
shotcrete.
Ensure that the thickness of shotcrete satisfies the minimum requirements as shown on the
approved Working Drawings using shooting wires, thickness control pins, or other acceptable
devices. Fill all depressions along the excavated face with shotcrete at no additional cost to the State.
Repair shotcrete surface defects as soon as possible after placement. Remove and replace
shotcrete which exhibits segregation, honeycombing, lamination, voids, or sand pockets. In-place
shotcrete determined not to meet the specified strength requirements will be subject to remediation.
Finish shotcrete with either an undisturbed gun finish as applied from the nozzle or a rough-
screeded finish.
Attach a bearing plate and nut to each nail head as shown on the approved Working Drawings.
While shotcrete is still plastic and before its initial set, uniformly seat the plate on the shotcrete by
hand wrench tightening the nut. Where uniform contact between the plate and the shotcrete cannot be
provided, set the plate in a bed of grout. After grout has set for 24 hours, tighten the nut using a hand
wrench. Ensure bearing plates with headed studs are in intimate contact with the construction facing
and the studs are located within the tolerances specified herein.
Locate the SNWS facing elements from the contract documents location and dimensions within
the tolerances provided in Table 211-3 SNWS Tolerances for Facing Elements:
TABLE 211-3 SNWS TOLERANCES FOR FACING ELEMENTS

Do not excavate to the next lift until nail installation, reinforced shotcrete placement,
attachment of bearing plates, and nuts and nail testing has been completed and accepted in the current
lift. Ensure nail grout and shotcrete have cured for at least 72 hours or attained at least their specified
3-day compressive strength before excavating the next underlying lift.
E. SNWS Testing. Perform preproduction verification, verification, and proof testing of designated
test nails. Perform a preproduction verification test and verification tests on sacrificial test nails as
described herein. Perform proof tests on production nails at locations selected by the Engineer and as
described herein. Do not load or perform nail testing until the nail grout and shotcrete facing have
cured for at least 72 hours and attained at least their specified 3-day compressive strength. Testing in
less than 72 hours will only be allowed if the Contractor submits compressive strength test results, for
tests performed by a qualified independent testing laboratory, verifying that the nail grout and
shotcrete mixes being used will provide the specified 3-day compressive strength in the lesser time.
Provide a minimum 3 ft. temporary unbonded length in each test nail. Prior to testing, grout only
the bonded length of the test nail. Determine the bonded length of the test nail based on the
production nail bar grade and sized such that the allowable bar structural load is not exceeded during
testing. The bond length shall not be less than 10 ft.
The maximum test load shall not exceed 80% of the GUTS of the nail. Monitor the jack load with
a load cell. Provide the Engineer with the calibration curve for the load cell before start of testing.
Submit two copies of all test data to the Engineer.
1. PreProduction Verification Test. Perform a preproduction verification test prior to
installation of production nails to verify the Contractor’s installation methods and nail pullout
resistance. Testing requirements are contained in §211-3.01 E. 2. Verification Testing.
2. Verification Testing. Perform a minimum of 2 verification tests in each different soil/rock
unit and for each different drilling/grouting method proposed to be used, at each wall
location. Verification test nails will be sacrificial and not incorporated as production nails.
Bare bars can be used for the sacrificial verification test nails.
Incrementally load verification test nails to a maximum test load of 3 times the design
load (P) in accordance with Table 211-4 SNWS Verification Test Load Schedule. Record soil
nail movements at each load increment.

AL 1 minute (record permanent set) 1P = Design Load
AL = Alignment Load. The AL necessary to maintain position of the stressing and testing equipment shall
not exceed 0.05 P. Set dial gauges to “zero” after the alignment load has been applied initially.
2The load hold portion of the verification test is a test load of 1.50 P, which shall be held constant for 60
minutes. The load hold time shall start when the pump begins to load the anchor from the 1.25 P load to
the test load. A load cell shall be used to monitor the constant load. Total movements with respect to an
independent fixed reference point shall be recorded at 1 minute, 2, 3, 5, 6, 10, 20, 30, 50, and 60 minutes.
Maintain load during the load hold portion of the test within 2% of the intended load by use of the load
cell.
All load increments shall be maintained within 5% of the intended load except as noted
for the load hold portion of the test.
The Department will review all verification tests to determine if the nail is acceptable. A
nail will be accepted if the following three criteria are met:
a. A total load hold movement of less than 0.08 in. per log cycle of time between the 6
and 60 minute readings is measured during load hold testing and the creep rate is
linear or decreasing throughout the load hold period.
b. The total measured movement at the maximum test load exceeds 80% of the
theoretical elastic elongation of the test nail unbonded length.
c. A pullout failure does not occur prior to the 2.50 P load increment. Pullout failure is
defined as the load at which attempts to further increase the test load simply result in
continued pullout movement of the test nail. Although the nail will be incrementally
loaded to a maximum test load of 3.00 P or failure, the test is deemed acceptable if
the nail adequately performs under load up to 2.00 P. The pullout failure load shall be
recorded as part of the test data.
3. Proof Testing. Perform proof testing on a minimum of 5% (1 in 20) of the production nails in
each row or a minimum of 1 per row. The locations shall be designated by the Engineer. A
verification test nail successfully completed during production work shall be considered
equivalent to a proof test nail and shall be accounted for in determining the number of proof
tests required in that particular row.
Production proof test nails shorter than 13 ft. in length may be constructed with less than
the minimum 10 ft. bond length with the unbonded length limited to 3 ft.
Incrementally load the proof test nail to a maximum test load of 1.5 times the Design
Load (P) in accordance with Table 211-5 SNWS Proof Test Load Schedule. Record the soil
nail movements at each load increment.

2Hold each load increment, except for the 1.5 P load, until the deflection stabilizes.
3The load hold portion of the proof test is a maximum test load of 1.50 P, which shall be held constant for
10 minutes. The load hold time shall start when the pump begins to load the anchor from the 1.25 P load
to the test load. A load cell shall be used to monitor the constant load. Total movements with respect to an
independent fixed reference point shall be recorded at 1 minute, 2, 3, 5, 6, and 10 minutes. If the total
movement between 1 minute and 10 minutes exceeds 1 mm, the test load shall be held for an additional
50 minutes. Total movements shall be recorded at 20, 30, 50 and 60 minutes.
All load increments shall be maintained within 5% of the intended load.
The Department will review all proof tests to determine if the nail is acceptable. A nail will
be accepted if the following three criteria are met:
a. A total load hold movement of less than 0.04 in. measured between the 1 and 10
minute readings or a total load hold movement of less than 0.08 in. is measured
between the 6 and 60 minute readings and the creep rate is linear or decreasing
throughout the load hold period.
b. The total measured movement at the maximum test load exceeds 80% of the
theoretical elastic elongation of the test nail unbonded length.
c. A pullout failure does not occur at the maximum test load. Pullout failure is defined
as the load at which attempts to further increase the test load simply result in
continued pullout movement of the test nail. The pullout failure load shall be
recorded as part of the test data.
Successful proof-tested nails meeting the above test acceptance criteria may be incorporated as
production nails, provided that:
1. The unbonded length of the test nail drillhole has not collapsed during testing.
2. The minimum required drillhole diameter has been maintained.
3. The specified corrosion protection is provided.
4. The test nail length is equal to or greater than the scheduled production nail length.
Test nails meeting the above requirements shall be completed by satisfactorily grouting up the
unbonded test length. Maintaining the temporary unbonded test length for subsequent grouting is the
Contractor’s responsibility. If the unbonded test length of production proof test nails cannot be
satisfactorily grouted subsequent to testing, the proof test nail shall become sacrificial and shall be
replaced with an additional production nail installed at no additional cost.
89 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
For nails that are unacceptable, the Contractor shall submit a written proposal containing a
suggested course of action.
Construct and attach any permanent facing and insulating materials shown in the contract
documents.
211-3.02. Grouted Tieback System (GTS).
A. GTS Submittal. Submit a design and design experience to the Engineer a minimum of 30
calendar days prior to start of work. Begin work only after receiving the Departments approval.
1. Experience. Submit as proof to the DCETS: (1) the names of two projects for which the
Contractor or subcontractor performing the work has successfully installed grouted tiebacks
within the past two years, (2) the foreman for this work having supervised the installation of
grouted tiebacks on at least two projects in the past two years. Submit proof of prior
experience with the subcontractor approval process.

Determine the tieback type, size and bond length necessary to develop adequate load
capacity to satisfy grouted tieback testing Acceptance Criteria for the design loads shown in
the contract documents and in accordance with the Post Tensioning Institute
Recommendations for Prestressed Rock and Soil Anchors. The minimum bond length shall be
10 ft. in rock and 15 ft. in soil. The minimum tendon bond length shall be 10 ft. The
minimum stressing length shall be 15 ft. or as shown in the contract documents, whichever is
greater. The tieback hole shall remain inside the right-of-way or easement limits shown in the
contract documents.
Provide working drawings conforming to the size and type requirements in accordance
with §718-01 Prestressed Concrete Units (Structural) A. Size and Type. Include the
following:
a. A grouted tieback schedule including:
i. grouted tieback number,
ii. design load for each tieback,
iii. type and size of tendon,
iv. total tendon length,
v. bond length, and tendon bond length if different from bond length,
vi. stressing length.

3. Report. Submit a report to the Engineer within 30 calendar days after completion of the
tieback work. The report shall contain:
a. as-built drawings showing the locations of the tiebacks, total tendon lengths, stressing
lengths and bond lengths,
b. prestressing steel manufacturer's mill test reports for the tendons,
90 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
c. tieback installation notes (hole progression, caving, clean-out),
d. grouting records indicating the cement type, quantity injected and grout pressures,
e. tieback test results and graphs.
B. GTS Installation. The holes for the tiebacks may be either driven or drilled. The hole shall not be
progressed in a location that requires the tendon to be bent in order to enable the bearing plate to be
connected to the supporting structure. If operations cause subsidence or physical damage,
immediately cease operations and repair the damage. The Contractor shall immediately revise
operations to prevent reoccurrence of such damage. Any and all costs incurred due to this subsidence
or physical damage shall be at no additional cost to the State. If the hole will not stand open, casing
shall be installed as required to maintain a clean and open hole. The hole diameter shall be no less
than 3 in. if using pressure grouting in the bond length and 4 in. if not using pressure grouting. The
Contractor shall provide a drill bit with a diameter no less than the specified hole diameter minus ⅛
in. The hole shall extend a minimum of 2 ft. beyond the tendon length. The holes shall be located in
elevation as shown in the contract documents, within a 3 in. tolerance. The holes shall be progressed
to the inclination and alignment as specified in the contract documents, within a ±3° tolerance. All
tieback holes shall be progressed perpendicular to the direction of the wall, as seen in the contract
documents. Holes in rock shall be thoroughly cleaned of all dust, rock chips, grease or other material
which may affect bond prior to inserting the tendon.
Strands shall not be coupled, except in the case of repairs of installed tendons or for extending
stressed strand anchors.
A water-tightness test will be required for all tiebacks bonded in rock if grout is injected at a
pressure of less than 50 psi. The water-tightness test shall be performed by filling the entire hole in
the rock with water and subjecting it to a pressure of 5 psi as measured at the top of the hole. If the
stressing length portion of hole is in soil or fractured rock, a packer or casing shall be used to allow
the bond length to be pressure-tested. If the leakage rate from the hole, over a 10 minute period,
exceeds 0.001 gal. of water per inch of hole diameter per foot of length of hole per minute, the hole
shall be grouted, redrilled and retested. Should the subsequent water-tightness test fail, the entire
process shall be repeated until results are attained which are within leakage allowances. If artesian or
flowing water is encountered in the drilled hole, pressure shall be maintained on the grout until the
grout has reached initial set.
The Contractor may eliminate the requirement for water-tightness tests in rock by using pressure
grouting techniques. Pressure grouting requires that the drill hole be sealed and that the grout be
injected until a 50 psi grout pressure, measured at the top of the hole, can be maintained on the grout
for 5 minutes without further grout injection.
In the bond length, centralizers and their installed locations shall be subject to approval by the
Engineer. Centralizers shall be provided at a maximum of 10 ft. center to center spacing throughout
the bond length so that not less than ½ in. of grout cover along the bond length is achieved. A
centralizer shall be provided at the bottom end of the tendon. Sag of the tendon shall be taken into
account when selecting centralizer diameter and spacing. Multi-element tendons shall also employ
spacers at maximum 10 ft. intervals throughout the bond length to ensure grout cover on all elements.
When the contract documents require encapsulation to provide double-corrosion protection for
the tendons:
1. The tendon shall be encapsulated in a grout-filled corrugated tube of one of the types stated in
the Materials section of this specification. The tendon may be grouted inside the
encapsulation either before or after inserting the tendon into the drill hole. The bond length of
the tendon shall be centralized to provide a minimum grout cover of 3/16 in. within the tube.
Spacers shall be used along the tendon bond length for multi-element tendons to ensure good
bond with the encapsulation grout.
2. Centralizers shall be used to provide a minimum of 5/16 in. of grout cover over the tendon
bond length encapsulation. Centralizers shall be securely attached to the encapsulation and
91 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
shall be spaced at no more than 10 ft. A centralizer shall be provided at the bottom end of the
tendon bond length encapsulation. A centralizer shall also be located a maximum of 5 ft. from
the top of the bond length.
The bond length of the tendon shall be free of dirt, manufacturer’s lubricants, corrosion-inhibiting
coatings or other deleterious substances prior to installation.
The tendon shall be inserted in the casing or hole without difficulty. If the tendon cannot be
completely inserted, the Contractor shall remove the tendon and clean or redrill the hole to permit
insertion. Partially inserted tendons shall not be driven or otherwise forced into the hole. Tendons
shall not be subject to sharp bends. Care shall be taken to prevent damage to the tendon's corrosion
protection and centralizers during handling and installation.
The grouting equipment shall be capable of continuous mixing and shall produce grout free of
lumps. The grout pump shall be equipped with a grout pressure gage capable of measuring the highest
working pressures attained plus 50 psi.
The annular space between the tieback and the drilled hole up to the level of the trumpet and
between the tendon and encapsulation shall be filled with grout. In order to prevent air voids in the
grouting operation, the hole shall be filled with grout progressively from bottom to top. Grouting of
the stressing length shall be done at low pressure. The trumpet shall not bear on the top of the
stressing length grout column during testing, to ensure that load applied to the tieback during testing
is not transferred to the anchorage via the grout column.
The tieback shall be centered in the trumpet so that there is no contact between the two. The
corrosion protection surrounding the stressing length of the tendon shall extend up beyond the bottom
seal of the trumpet but shall not contact the bearing plate or anchor head during stressing and testing.
The anchor head shall be protected from corrosion during the interim between tieback installation
and final corrosion protection installation by installing a temporary cap and filling the trumpet and
anchor head with corrosion-inhibiting grease. Any detrimental corrosion shall be caused for rejection.
After installation, testing and acceptance of each tieback, the trumpet shall be filled with grout or
corrosion inhibiting grease and the permanent corrosion protection of the anchorage shall be installed.
The Contractor shall either:
1. place a water-tight steel cap, filled with corrosion inhibiting grease or grout, over the anchor
head, or
2. encase the anchor head in concrete.
C. GTS Testing. Each tieback shall be tested. At no time shall a test or temporary load on any
tendon exceed 80% of the GUTS of the tendon. The following tests are required:
1. Performance Tests: The first two anchors installed at each specified design load capacity and
5% of the remaining anchors shall be performance tested. These tests are used to determine
residual movements.
2. Creep Tests: Creep tests shall only be performed where specified by a Special Note in the
contract documents. These tests are performed to determine long term deformation behavior
in plastic soils.
3. Proof Tests: Proof tests shall be performed on all anchors not performance or creep tested.
These tests are used to verify load capacity.
4. Lift-Off Readings: Lift-off readings shall be taken on all tiebacks after the load has been
transferred to the anchorage but prior to removing the jack.
5. Lift-Off Tests: Lift-off tests shall only be performed on tiebacks in rock. If required, lift-off
tests shall be performed on at least 2 tiebacks at locations to be chosen by the Engineer.
Additional tests, up to 10% of the total number of tiebacks may be directed by the Engineer.
Copies of all test results and graphs shall be transmitted to the Director, Geotechnical
Engineering Bureau as each test is completed.
92 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Jacks shall have ram travel at least equal to the theoretical elastic elongation of the stressing
length plus the bond length at the maximum test load, and be sufficient to accommodate wall
movements. A pressure gauge shall be used with each jack. Gauges shall be calibrated with a single
jack and shall not be used with any other jack. All gauges shall be accurate enough to read 100 psi
changes in pressure. For performance and creep tests, the jack used shall have two calibrated gauges;
a master gauge and backup gauge. The pump shall be capable of applying each load increment in less
than 60 seconds.
A load cell, which has been calibrated by an independent testing laboratory within 14 days prior
to the start of work and at least annually thereafter, shall be used to measure the small changes in load
during the load hold portion of the performance and creep tests. There will be no substitute for the
load cell on testing of the performance and creep tests. Load cells are not required for proof tests. The
Contractor shall provide the Engineer with the calibration curve for the load cell prior to testing.
For the performance and creep tests, the master gauge and backup gauge shall be connected to the
same pressure hose between the pump and jack and be used to measure the applied loads. If the load
measured by the master gauge and backup gauge differ by more than 10%, the jack, master gauge and
backup gauge shall be recalibrated as a unit at no expense to the State.
At the completion of the test the tieback load shall be adjusted to the lock-off load and transferred
to the anchorage.
The movement of the tieback tendon at each load increment shall be recorded to the nearest 0.001
in. relative to an independent, fixed reference point.

SECTION 212 – ROCK SLOPE REINFORCEMENT AND CATCHMENT SYSTEMS (Last Revised January 2019)
212-1 DESCRIPTION. This work shall consist of furnishing and installing rock slope stabilization
techniques or roadside protective measures in conformance with payment lines, type, size, and at the
locations specified in the contract documents.
212-1.01 Definitions.
A. General. As outlined in Section 203 Excavation and Embankment, all rock slopes shall be
thoroughly scaled and cleaned of unsound material and loose masses of rock. This section provides
requirements for specific techniques developed to address situations where a hazardous rock slope
situation still exists after stripping and scaling in order to control a rockfall within a designated
rockfall catchment area.
B. Rock Fall. A rockfall is the movement of rock from a slope that is so steep the rock continues to
move down slope. The movement may be by free falling, bouncing, rolling or sliding.
C. Rock Catchment Area. The rockfall catchment area is defined as the area between the edge of
roadway pavement and the base of an adjacent rockslope that is used to restrict rockfall from reaching
the roadway. The term catchment area is synonymous with ditch, rockfall ditch, rockfall catch ditch
and rock fallout area. The catchment area width is the horizontal distance between the roadway edge
of pavement and the base (toe) of a rockslope.
D. Rock Catchment Fences. Rock catchment fences are techniques to control rockfalls within the
R.O.W. Rock catchment fences are wire or cable mesh draped from support columns situated to
define the catchment area. The catchment fence, or impact section, attenuates the rockfall energy to
capture the falling rock and maintain it within the catchment area.
E. Rock Mesh Slope Protection. Rock mesh slope protection is a technique to control rockfalls
within the R.O.W. Rock mesh slope protection is the placement of wire or cable mesh on a slope face.
The mesh controls the descent of falling rock, which accumulates near the base of the slope within the
catchment area.
212-2 MATERIALS
212-2.01 Wire Rope Rock Catchment Fence. The rock catchment fence system, as obtained from the

302-3.01 Weather Limitations for Option A. This work will not be permitted on a subbase or subgrade
containing frost, nor when the temperature of the surface on which the mixture is to be placed is below
45°F. All material placed under this section during any calendar year shall be mixed after March 1 of that
year. No material shall be placed from the last Saturday of September to May 15, except with written
permission of and under such special limitations and conditions as may be imposed by the Deputy Chief
Engineer (Technical Services).
302-3.02 Equipment for Mixing Option A. All equipment for this work shall be subject to approval of
the Engineer at all times. No work under this section will be permitted until all equipment and the
processing facilities are established, inspected and approved.
Mixing shall be done with a rotating paddle shaft pugmill, providing suitable pressure-kneading
action in mixing. Mixing by blading, shoveling and/or scooping will not be permitted.
The materials shall be mixed either at a central twin shaft pugmill mixing plant by the plant mix
method, or on the roadbed (or some other area approved by the Engineer) by a traveling twin shaft
pugmill, whichever equipment the Contractor elects to use.
The mixer shall be either a continuous or a batch type pugmill, designed to accurately proportion
either by volume or by weight, so that when the granular material and bituminous material are
incorporated in the mix, a thorough and uniform coating of the granular material will result. The pugmill
mixer shall be provided with weighing, volumetric or other gauging equipment which shall be capable of
providing accurate control at all times of the amount of granular material entering the mixer per time
interval. The mixer shall be equipped to mechanically interlock the bituminous feed with the granular
material feed, such that uniformity of the mixture is assured at all times. A water pump with meter shall
be available to add water to the granular material, just prior to the addition of the bituminous material.
The mixer shall be equipped with a positive displacement meter for totalizing the quantity of
bituminous material applied to the mixing chamber. A by-pass valve shall be placed on the bituminous
line between the positive displacement meter and the spray bar in the pugmill to permit determination of
the accuracy of the positive displacement meter. The Contractor shall furnish a clean 55 gallon drum
having one end completely open, and a length of flexible hose to permit filling from the by-pass valve on
the bituminous line.
111 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Traveling pugmill mixing equipment shall not be operated at speeds greater than those recommended
by the manufacturer for the depth of treatment and quantity of material used.
Where the materials are mixed at a central twin shaft pugmill mixing plant, the pugmill mixing
chamber shall extend at least 4 feet beyond the last point where the granular material, binder, and water
are fed into the mixer, so that all materials will be completely and thoroughly mixed in the pugmill for a
distance of at least 4 feet. The pugmill paddles shall be of a type adjustable for angular position on the
shaft, and shall be reversible to allow retardation of the flow of the mixer, in order to control the mixing
time. A dam or baffle, if approved in writing by the Director, Geotechnical Engineering Bureau may be
used for the purpose of retarding flow. A mechanically operated discharge hopper of at least 1 cubic yard
capacity shall be provided. Sufficient clearance for a ten wheel dump truck shall be provided beneath the
discharge hopper to permit calibration.
302-3.03 Stockpiling and Sampling for Option A. Before mixing with the bituminous material, the
granular material shall be stockpiled, sampled and tested for approval as stipulated in §302-2.02.
302-3.04 Mixing for Option A. The proportion of bituminous material that shall be mixed with the
granular material will range between 16 and 19 gallons per cubic yard, loose (uncompacted) measure. The
actual proportion within this range, however, shall not be less than that determined by the Geotechnical
Engineering Bureau and specified by the Engineer after the stockpiled granular material is sampled and
tested. In computing the rate of application, the loose measure volume shall be determined by level filling
a truck, having a minimum capacity of 8 cubic yards, with granular material. No mixing will be allowed
until the temperature of the granular material is 45°F or higher.
The moisture content of the granular material, based on the material passing 3/4 inch sieve, just prior
to the addition of the bituminous material, shall be in the range of 4 to 8 percent. The acceptable moisture
content within this range shall be determined by the Engineer.
All granular material removed from stockpiles for introduction into continuous twin shaft or traveling
twin shaft pugmill mixers shall be by side excavation for the full height of the stockpile unless otherwise
approved in writing by the Director, Geotechnical Engineering Bureau.
If mixed in a traveling plant, the method of transporting and introducing granular material from
approved stockpiles into the mixer shall be as approved by the Engineer.
The application temperature of the bituminous material shall be designated by the Engineer and be
within the range of 130°F to 170°F.
After the granular material and bituminous material have been introduced into the pugmill, the mixing
shall continue for a length of time necessary to uniformly coat the particles and to obtain a homogeneous
mixture.
The discharge gates in a central plant shall not remain open during production of the stabilized
mixture and shall only be opened in order to empty the hopper after the hopper becomes full. The
discharged mixture may be immediately transported directly to the grade or stockpiles for later use.
The material shall be transported to the stockpile by dump truck haul. If the Contractor wishes to
utilize a method other than dump truck haul to construct stockpiles, a request shall be submitted to the
Director, Geotechnical Engineering Bureau. The request shall include the proposed method and type of
equipment to be used.
Approval, if granted, will be based on the opinion of the Director, Geotechnical Engineering Bureau
as to the capabilities of the proposal to provide a stockpile of uniformly mixed, uncontaminated material.
If granted, such a waiver will remain in force only so long as all conditions for which the waiver is
granted remain unchanged and a satisfactory material results.

116 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
307-3 CONSTRUCTION DETAILS
307-3.01 Equipment. No work will be permitted until all necessary equipment is on hand, inspected and
approved by the Engineer.
A. Scarifiers. A grader-scarifier, heavy disc harrow, heavy plow or rotary pulverizing mixer shall be
used for the initial scarification of the soil. The equipment shall be capable of scarifying the soil to the
full depth of stabilized treatment.
B. Mixers. A rotary pulverizing mixer or heavy plow shall be used for all mixing of the hydrated
lime with the subgrade soil. The use of a heavy plow will be permitted only if the rotary pulverizing
mixer is not capable of adequately mixing the lime-soil mixture to the full depth of treatment. Rotary
mixers shall be equivalent to the Seaman Duo-Stabilizer Model DS730 or the Brothers Master Mixer
Model LSPRM84A.
C. Lime Spreaders. Spreading equipment shall be capable of uniformly distributing the lime without
excess loss and at a specified rate.
D. Compactors. Compaction equipment shall be selected as specified in Section 203, Compaction.
E. Shaping. Shaping of the stabilized course shall be accomplished with a motor-grader or
equivalent equipment capable of shaping the surface to the required tolerances specified.
F. Finish Rolling. A smooth steel wheel tandem roller weighing between 8 to 10 tons shall be used
for the finish rolling.
G. Water Equipment. Water shall be added to the soil with a pressure distributor or other suitable
equipment capable of uniformly distributing the required amount.
307-3.02 Weather Limitations. Lime stabilization of the subgrade shall not be done when the subgrade
temperature is below 40°F, nor in the period from October 15 to May 15, except by written permission of
and under such special limitations as set forth by the Deputy Chief Engineer (Technical Services). The
hydrated lime shall not be mixed with frozen subgrade soil or when the subgrade contains frost. Lime
shall not be applied when wind conditions, as determined by the Engineer, are such that blowing lime
becomes objectionable or hazardous to traffic, workers, and adjacent property owners.
307-3.03 Protection and Safety. Before lime is spread, the Contractor shall take necessary precautions
and provide necessary equipment to protect all personnel and adjacent properties from lime dust created
by the lime application and mixing operations. Safety goggles and lightweight filter masks shall be
provided by the Contractor to all working personnel and shall be worn at all times during these
operations.
307-3.04 Preparation of Foundation. Prior to the addition of any lime to the subgrade, the area to be
stabilized shall be graded and shaped in close conformity to the typical sections, lines and grades as
shown on the plans or as specified by the Engineer. Where the depth of lime stabilization exceeds 6
inches, the subgrade soil in excess of the 6 inches depth shall be removed, placed in windrows and
processed as an additional lift.
307-3.05 Scarifying. The subgrade soil shall be scarified 6 inches deep to the width required for
stabilization. The scarified material shall be partially pulverized by making one pass through the area with
a pulverizing rotary mixer. The pulverizing portion of the scarifying operation may be deleted in some
117 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
areas, where, as determined by the Engineer, the subgrade soils are excessively wet and sticky so that
pulverizing with a rotary mixer is impractical.
307-3.06 Application of Lime. The hydrated lime shall be applied to the scarified material by an
approved method and at the rate stipulated in the plans or as specified by the Engineer. A lime slurry,
applied by an approved method and suitable equipment, will be permitted. Spreading equipment shall
uniformly distribute the lime without excess loss. No equipment except that used for spreading and
mixing shall be permitted to pass over the spread lime until it is mixed. The Engineer may require the
spread lime to be sprinkled with water to reduce dusting.
307-3.07 Primary Mixing. After the required amount of lime has been uniformly spread, it shall be
mixed into the subgrade to the full depth of treatment using a traveling rotary mixing machine or heavy
plow. A minimum of three passes will be required to assure uniform incorporation of the hydrated lime.
Water shall be added at the rate of up to 500 gallons/ton of lime as required for the proper consistency.
The primary mixing operation shall be completed within four hours after application of the lime. At
this time, all of the lime shall be thoroughly and uniformly incorporated into the subgrade to the full depth
of treatment in such a manner that the result is a homogeneous, friable mixture of subgrade soil and lime,
free from clods or lumps exceeding 2 inches in size. Where the required depth of stabilization exceeds 6
inches, the windrowed material in excess of the 6 inches depth shall be spread to the required lift
thickness and processed, by the addition of lime and primary mixing, as specified for the first layer. Each
additional layer, where required, shall be processed similarly.
Immediately after the primary mixing operations are completed for the full depth of treatment, the
surface of the subgrade shall be shaped and lightly sealed with a pneumatic tired or smooth steel wheel
roller. The surface shall be crowned so as to properly shed water if rain occurs.
307-3.08 Curing. Following primary mixing operations, the stabilized course shall be allowed to cure
for at least 24 hours plus any additional time required for the lime to properly react with the subgrade soil.
Curing periods in excess of 24 hours shall be as determined and specified by the Engineer. During the
curing period, the surface of the material shall be kept moist to prevent drying and cracking, and
maintained in a properly sealed and crowned condition as specified by the Engineer.
307-3.09 Secondary Mixing. Immediately after the completion of the curing period, the stabilized
course shall again be completely mixed and pulverized to the full depth of stabilization by a rotary
pulverizing mixer. Secondary mixing shall continue for at least three passes or until, as determined by the
Engineer, the material is properly mixed and blended. Adjustments in water content shall be made during
the secondary mixing operation to obtain the proper moisture content required for compaction.
307-3.10 Compaction, Shaping and Finishing. Compaction of the mixture shall begin immediately
after completion of the secondary mixing operations and after the proper moisture content for compaction
has been obtained. Compaction shall be in accordance with the requirements of Section 203,
Compaction. After compaction and shaping, the surface of the course shall be finished-rolled by a
smooth steel wheel tandem roller weighing between 8 to 10 tons. The secondary mixing, compaction,
shaping and finishing operations shall be completed within eight hours after the start of the secondary
mixing.
The surface of the finished stabilized subgrade course shall not extend above design grade at any
location.
The thickness of the complete hydrated lime stabilized subgrade will be determined from measurements
made in test holes located at random intervals not to exceed 500 feet. The measured thickness shall not
deviate from that shown on the plans or specified by the Engineer, by more than plus 1 1/2 inches or minus
1 inch. Areas of hydrated lime stabilized subgrade not meeting the specified thickness requirements shall
be reconstructed.
118 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The subbase course material shall be placed and compacted within two days after the lime stabilized
subgrade course has been compacted, shaped and finished at that location. The surface of the treated
subgrade shall be kept continuously moist up to the time of subbase material placement.
307-3.11 Surface Treatment Option. The Contractor may elect to defer placement of the subbase
materials up to two weeks by placing a bituminous membrane, cationic asphalt emulsion, over the treated
subgrade. The bituminous membrane must be placed within two days after the stabilized subgrade has
been compacted and finished. The stabilized subgrade must be kept continuously moist prior to
application of the bituminous membrane. The bituminous material shall be applied at a uniform rate of
0.2 gal/sy of treated subgrade. Where traffic is to operate on the treated subgrade, the bituminous
membrane shall be chipped with a uniform coating of Size 1A aggregate applied at a rate of 15 lb/sy of
treated subgrade.

the normal hardening of the soil cement mixture, and shall be subject to the approval of the Engineer at all
times. The soil will be sampled by the Engineer prior to use and submitted to the Geotechnical
Engineering Bureau to determine both its suitability and the cement content to be used. Frozen soil or soil
containing frost shall not be used.
The soil material shall be stockpiled, sampled and tested before mixing in conformance with material
tests and quality control methods contained in the appropriate Department publications which are current
on the date of advertisement for bids. These publications are available upon request to the Regional
Director or the Director, Geotechnical Engineering Bureau.
308-3 CONSTRUCTION DETAILS
308-3.01 Equipment. No work under this item will be permitted until all equipment and facilities
involved are established, inspected and approved by the Engineer.
The materials shall be mixed in a central twin-shaft pugmill mixing plant or mixed on the roadbed by
a traveling pugmill, whichever equipment the Contractor elects to use. Traveling pugmill mixing
equipment shall not be operated at speeds greater than those recommended by the manufacturer for the
depth of treatment and quantity of materials to be mixed.
Where the materials are mixed in a central twin-shaft pugmill mixing plant, the mixing area of the
pugmill shall extend at least 4 feet beyond the last point where the soil, cement, or water are fed into the
mixer, so that all materials will be completely and thoroughly mixed in the pugmill for a distance of at
least 4 feet. The paddles of the pugmill shall be adjustable for angular position on the shaft, and shall be
reversible to retard the flow of mixture in order to control the mixing time. Where the materials are mixed
at a central twin-shaft mixing plant, a hydraulically or mechanically operated discharge hopper of at least
1 cubic yard capacity shall be provided. Sufficient clearance for a ten-wheel dump truck shall be provided
underneath the hopper.
The central mixer shall be either a continuous or batch type pugmill, and shall be designed to
accurately proportion the mix either by volume or by weight. The pugmill mixer shall be provided with
weighing, volumetric or other gauging equipment, which shall be capable of providing accurate control at
all times of the amounts of soil and cement entering the mixer per time interval. The mixer shall be
equipped with a method of mechanically interlocking the cement feed with the soil feed so that uniformity
of the mixture will be assured at all times. A water pump and meter arrangement shall be available for
addition of water to the soil and cement. The water supply line shall have a 90° T connection with a valve
immediately downstream of the flow meter for calibration purposes. The meter shall be calibrated at least
once a year under the direction of Department personnel.
A smooth steel wheel roller and a self-propelled pneumatic tired or self-propelled vibratory
compactor shall be used for compaction. The minimum number of passes shall be determined by the
Engineer, after field tests, and shall be such as to produce the specified minimum density for the full
depth of the course. Cleated or tracked equipment will not be permitted on the soil cement course. In
areas inaccessible to pneumatic tired compactors, or where maneuvering space is limited, impact rammers
and/or vibratory equipment may be used provided the required density is obtained.
Equipment suitable for storing, handling, weighing, measuring, proportioning, controlling and
applying or spreading the cement shall be used.
120 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Equipment suitable for accurately metering, controlling and applying the water shall be used. If a
pugmill mixer is used, all necessary water for mixing shall be added in the pugmill. If a rotary mixer is
permitted and used, water for mixing shall be added through a spray bar in the mixing chamber.
308-3.02 Weather Limitations. Soil Cement Course shall not be placed between October 15 and May
15 nor when the air temperature in the shade is 40°F or lower. Soil cement course shall not be placed
upon a frozen surface.
308-3.03 Preparation of Foundation. Before soil cement operations are begun, the area upon which the
soil cement course is to be placed shall be graded, shaped, and compacted as required in conformance
with the grades, lines, thicknesses and typical sections shown on the plans or as ordered by the Engineer.
The subgrade and any preceding course shall be compact and suitable to support the construction and
compaction equipment without settlement or displacement. Soft or yielding subgrade shall be corrected
and made stable before the soil cement course is placed.
308-3.04 Application of Calcium Chloride and Cement. Where required by a Special Note in the
Proposal, the specified quantity of calcium chloride ordered by the Engineer in flake form shall be
uniformly added to the soil before adding the cement.
Portland cement, in the amount ordered by the Engineer, shall be added uniformly to the soil material.
The amount of cement ordered by the Engineer will range generally between 8 percent and 10 percent by
weight.
The percentage of moisture in the soil, at the time of cement application, shall not exceed the quantity
that will permit a uniform mixture of soil and cement during mixing operations and shall not exceed the
optimum moisture content for the soil cement mixture, as determined by the Engineer.
Where a traveling pugmill mixer is used, cement that has been displaced or removed from the
windrow regardless of cause, shall be replaced before mixing is started, at the Contractor's expense.
308-3.05 Mixing and Spreading. Immediately prior to mixing, the soil shall have a minimum
temperature of 40°F. After the cement has been applied to the soil, it shall be immediately mixed with the
soil. Mixing shall continue until the cement has been thoroughly blended with the soil to prevent the
formation of cement balls when the water is applied. Immediately after the soil and cement have been
thoroughly mixed, the full amount of water shall be applied uniformly and mixing shall be continued until
an intimate and homogeneous blend of soil, cement and water has been obtained.
When water application and mixing have been completed, the percentage of moisture in the mixture
based on oven-dry weights, shall not be below, nor more than 2 percent above, the specified optimum
moisture content determined by the Engineer.
In order to minimize segregation of the mix, the discharge gates shall be kept closed until the hopper
is filled to at least one-half of its capacity. After the hopper is emptied, the gates shall be closed until the
hopper is refilled. The material shall then be discharged into clean trucks and transported directly to the
grade.
The soil cement shall be spread on an accepted subgrade or preceding course immediately after
mixing. If mixed in a central plant, approved mechanical spreading equipment shall be used and not more
than 30 minutes shall elapse between the time of mixing the cement and the start of the compaction
operation.
In case of rain between the time of adding cement and final finishing, the Engineer shall be the sole
judge of what areas involved are satisfactory and what areas are not acceptable. Areas not acceptable to
the Engineer shall be removed to the full depth of the soil cement course and properly replaced at the
Contractor's expense for all labor, materials and equipment involved.
308-3.06 Compaction. Prior to the beginning of compaction, the mixture shall be in a loose condition
for its full depth on the subbase course. As an immediate continuation of mixing operations, and after an
121 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
initial breakdown pass with a smooth steel wheel roller, the loose mixture then shall be uniformly
compacted, by a self-propelled pneumatic tired or self propelled vibratory compactor, to the specified
density. All areas and portions of this course shall be thoroughly and uniformly compacted for the full
thickness of the course to a minimum dry density of 95 percent of the maximum density. During
compaction, water shall be applied to the surface as determined and ordered by the Engineer, to maintain
the optimum moisture content.
308-3.07 Finishing. During the compaction operations, shaping will be required to obtain the required
surface and cross-section. During shaping operations it may be necessary to lightly scarify and broom-
drag the surface in order to remove ridges or depressions in excess of the permitted tolerance. The
resulting surface shall then be rolled with a smooth steel wheel roller, weighing not less than 10 tons, or
pneumatic tire rollers, or both. The final rolling shall be done by a smooth steel wheel roller. Several
applications of water may be required to keep the surface at the proper moisture content, as ordered by the
Engineer, during the finishing operation. Water shall be applied by the pressure spray bar method.
Compaction and finishing shall be done in such a manner as to produce, in not longer than 2 1/2 hours
after completion of mixing, a smooth, dense surface, free of surface compaction planes, cracks, ridges or
loose material. Immediately after rolling, the surface of the course shall be tested for trueness,
transversely and longitudinally. The finished surface of the course shall not extend above, nor be greater
than 1/2 inch below, true grade and surface at any location. Surface finishing shall be completed in
daylight hours.
Any portion of this course which has a density less than that specified shall be corrected or removed
and replaced to its full depth to meet these specifications, at the Contractor's expense.
308-3.08 Construction Joints. At the end of each day's construction, a straight transverse and/or
longitudinal construction joint shall be formed by cutting back into the completed work to form a true
vertical face, which shall be properly maintained until the abutting section is completed.
308-3.09 Curing and Surface Treatment. After the soil cement course has been finished as specified
herein, it shall be continually protected against drying by the application of water, until the bituminous
seal is applied. At least 48 hours shall elapse between the completion of the finishing operations and the
application of the bituminous seal.
At the time the bituminous seal is applied, the soil cement surface shall be dense, free of all loose and
extraneous material, and shall contain sufficient moisture to prevent penetration of the bituminous
material. Water shall be applied in sufficient quantity to fill the surface voids of the soil cement
immediately before the bituminous seal is applied. The bituminous seal shall be uniformly applied to the
surface of the completed soil cement at the rate of approximately 0.15 to 0.30 gal/sy with approved
heating and distributing equipment. The exact rate and temperature of application to give complete
coverage without excessive run-off will be as determined and ordered by the Engineer. No traffic, nor
placement of an overlying course, will be permitted over the soil cement course within 5 days from the
application of the bituminous seal. Where this course is utilized for maintaining traffic, the application of
the bituminous material shall be immediately followed by the application of approved cover aggregate of
1A size at the rate of 20 to 30 lb/sy. The aggregate will be broomed and rolled as ordered by the
Engineer.
When the air temperature may be expected to reach the freezing point, sufficient protection from
freezing shall be given the soil cement for 7 days after its construction and until it has hardened to the
satisfaction of the Engineer.
308-3.10 Traffic. No traffic or hauling equipment other than that necessary for sealing, chipping or for
placing the next course will be permitted over this course, unless specifically permitted by a Special Note
in the Proposal.

308-3.11 Maintenance. The Contractor shall be required, within the limits of the contract, to maintain
the soil cement in good condition and in a manner satisfactory to the Engineer from the time he first starts
work until all work has been completed and accepted. Maintenance by the Contractor shall include
immediate repairs of any defects, regardless of cause, that may occur. This work shall be done by the
Contractor at its own expense, and repeated as often as may be necessary to keep the course continuously
intact. Repairs are to be made in a manner to insure restoration of a uniform surface and durability of the
part repaired. Faulty and damaged work, regardless of cause, shall be replaced for the full depth of the
course by the Contractor at its own expense. Any low areas, regardless of cause, shall be remedied by
replacing the material for the full depth of the course and not by adding a thin layer of soil cement to the
completed work.
308-4 METHOD OF MEASUREMENT. The quantity to be paid for under this item will be the
number of cubic yards of material computed within the payment lines shown on the plans or otherwise
ordered in writing by the Engineer, and completed in accordance with the plans and specifications. The
thickness of the surface treatment will not be included in the volume measured for payment.
308-5 BASIS OF PAYMENT. The unit bid price per cubic yard for this item will include the cost of
furnishing all labor, equipment and materials necessary to complete the work, except that furnishing
Portland cement, calcium chloride (where required), bituminous material, water equipment and applying
water, will be paid for separately under their respective items.

402-3.05 Conditioning of Existing Surface. When specified in the contract documents, clean the surface
of the existing pavement, fill joints and cracks, and level the surface to a uniform grade and cross slope
prior to the application of a new HMA course in accordance with the provisions of Section 633 Conditioning
Existing Pavement. Clean any foreign material from the pavement resulting from construction operations
at no additional cost to the State.
Fill any depressions and wheelpath ruts prior to paving Truing and Leveling course using Table 402-2
Mixture Selection for Filling Wheelruts & Depressions, to select the appropriate mixture type.

If a Truing and Leveling (T&L) course is specified in the contract documents, place the course(s) of a
minimum variable thickness of proper plant mixture necessary to bring the surface of the existing pavement
to the same transverse slope and longitudinal grade required for the finished pavement surface. Use
Table 402-3 Mixture Selection for T&L Course, to select the appropriate mixture type. Select a mixture
such that dragging of stones at the thin edge is minimized, including when constructing wedges for super-
elevation. If dragging is excessive in any T&L course, select a different T & L mixture for the application.
The surface of this course will be tested in the same manner prescribed in §402-3.10 Surface Tolerance,
ensure that the allowable variation from the true surface after compaction does not exceed ⅜ inch.

402-3.06 Spreading and Finishing
A. Tack Coat. Apply tack coat between all HMA pavement lifts prior to placing HMA mixture
regardless of time period between lifts. Do not apply tack coat more than 24 hours prior to the placement
of HMA mixture unless approved by the Engineer. Apply tack coat to all contact surfaces of existing
HMA and Portland Cement Concrete including such areas as adjacent pavement edges, curbing, gutters,
manholes, and other structures where the HMA mixture will be in contact. Tack coat is not required
on the surface of Permeable Base courses. Paving over a tack coat should not commence until the
emulsion has broken (goes from brown to black) or is tacky when touched.
B. Joint Adhesive. Apply joint adhesive to all pavement edges in accordance with Section 418 Asphalt
Pavement Joint Adhesive prior to placing the asphalt mixture in order to provide bonding with the newly
laid pavement. The application of joint adhesive is for Top Course only unless it is specified for other
courses in the contract documents or as required under §402-3.01E. Scheduling HMA Placement.
C. HMA Mixture Temperature. For 50, 60, and 70 Series compaction methods, select a desired HMA
mixture temperature to be delivered within the mixing and compaction range of 250°F and 325°F, or
133 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
as recommended by the PG Binder manufacturer. Notify the Engineer of the desired delivery
temperature. Produce and deliver HMA mixtures to the work site, and incorporate into the work within
20°F of the specified temperature. For 80 Series compaction method, select the desired mixture
temperature with the concurrence of the Engineer.
D. HMA Mixture from Multiple Plants. Do not supply HMA mixture from multiple plants to a single
paver.
E. Reference Line. Erect and maintain taut reference line positioned at or near the pavement centerline
or edge to guide the paver when the initial pavement course is laid for new or reconstructed pavement.
Support the reference line at approximately 25 foot intervals on tangent sections and at closer intervals
on curves. Tension the line sufficiently to remove any sagging. Use a moving reference of at least 30
feet in length in lieu of a reference line with approval of the Engineer. The moving reference may be a
floating beam, ski, or other suitable type such that the resulting pavement course surface is even. A
short ski or shoe may also be used for the initial course with the approval of the Engineer if a satisfactory
fixed reference such as a curb, gutter, or other fixed reference is adjacent to the pavement. Any course
in an adjacent lane may be used as the reference for the use of a short ski. If the proposed floating beam
or the short ski does not produce the results similar to those obtained using a taut reference line,
discontinue the use of these devices and erect a taut reference line.
Automatic screed controls are not required for shoulders, temporary detours, behind curbs, where
existing grades at roadway intersection or drainage structure must be met, or in other areas where its
use is impractical.
F. HMA Mixture Placement. Use HMA paver(s) to place the HMA mixture either over the entire
width or over a partial width that is practical. Operate the paver at a consistent steady speed, correlated
to the rate of material delivery, in order to produce a mat free of bumps and dips, resulting in a smooth
ride. Place the HMA mixture on a clean, dry, tack-coated surface. Ensure trucks deliver the mixture
into the paver upon arrival at the site. Immediately spread and strike off HMA mixture to the required
width and loose depth to established line and grade, to obtain the required compacted thickness at the
completion of work. If the areas to be paved are less than 1,000 square feet or small and scattered, the
HMA mixture may be spread by hand or other method approved by the Engineer. For these areas, dump
and spread the mixture such that the compacted thickness meets the thickness specified in the contract
documents.
Place all pavement courses using one of the reference line methods required above. Prior to the
beginning of rolling, check the loose mat, adjust any irregularities, and remove and replace all
unsatisfactory material.
When filling wheel ruts with Shim Course, 6.3 Top Course or 9.5 Top Course mixture in an existing
pavement, place mixture in each wheelpath rut separately. Use a drag box configuration or approved
equal having side forms to shim the ruts. Spread and strike off the Shim Course material to a uniform
width of approximately 4 feet. The intent of the operation is to fill the low area only and not to place
the material over the pavement's full lane width. Ensure the placement equipment wheels and/or other
appurtenances do not interfere with the distribution and placement of the Shim Course material.
G. Top Course Texture and Color. Supply Top Course HMA mixture from a single plant for the
duration of the work such that the pavement surface has a uniform color and texture, except when a
contract includes multiple paving sites, or the paving length is more than 5 miles and supply from
multiple plants to either end of the paving length is practical. In that case, the above requirement will
apply to each paving site and locations at either end of the paving length as approved by the Regional
Materials Engineer. Limits of each site will be subject to approval by the Regional Materials Engineer.
If a plant breaks down, another plant may supply mixture if the aggregate used for producing the HMA
mixture is from the same source, with the concurrence of the Regional Materials Engineer. When
134 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
tandem paving is utilized, multiple plants may be used to supply mixture provided the aggregate used
is from the same source. The provisions of §402-3.06 D apply.
402-3.07 Compaction. Compact the HMA mixture sufficiently using the appropriate compaction method
specified in Table 402-4 Compaction Methods, to achieve pavement densities in a range of 92% to 97%,
expressed as a percentage of the mixture’s maximum theoretical density (MMTD).
When compacting HMA mixture using 50, 60, or 70 series methods, control all operations of the rollers
including speed, amplitude settings, vibration frequency, and the type of rollers.
Compact the HMA mixture using rollers meeting the requirements of §402-3.04 Rollers. Compact the
HMA mixture immediately after placement, and when the mixture is in the proper condition such that the
rollers do not cause displacement, cracking, or shoving. Initially, compact all courses with the roller
traveling parallel to the centerline of the pavement, beginning at each edge and working toward the center.
Compact super-elevated curves starting at the low-side edge and working toward the higher edge.
Immediately correct any displacement caused by reversing the direction of the roller, or any other
causes, using rakes and additional HMA mixture as required. Exercise care in rolling so as not to displace
the line and grade of the edges of the HMA mat. Keep the wheels properly moistened with water, water
mixed with small quantities of detergent, or other approved material, to prevent adhesion of the mixture to
the rollers. Do not use petroleum products or solvents.
Upon completion of the HMA mixture placement, ensure there are no visible defects in the pavement,
such as shallow ruts, ridges, roller marks, cracking, tearing, segregation, bleeding, or any other
irregularities. Correct any defects that become apparent or replace the defective pavement at no additional
cost to the State.
Compact the HMA mixture along forms, curbs, headers, walls, and other areas not accessible to rollers
with mechanical tampers. On depressed areas, use a trench roller or a small vibratory roller with the
approval by the Engineer.
Remove any HMA mixture that becomes loose and broken, mixed with dirt, or is in any way defective
and replace with fresh HMA mixture. Compact the HMA mixture to conform to the surrounding area.
Correct any area showing an excess or deficiency of HMA material.
Make a minimum of three passes of a pneumatic rubber tire roller for compaction when Shim Course,
6.3 Top Course or 9.5 Top Course is used for filling wheel ruts. Make a minimum of two passes when Shim
Course is used as a skim coat. Use other types of rollers with the approval of the Engineer.
Do not use vibratory compaction when HMA mixture is placed on structural bridge decks or other
structures with less than 2 feet of cover over the structure or when specified in contract documents. If
vibratory compaction is used, repair all damages which may occur to the highway components and adjacent
property, including buried utility and service facilities, at no additional cost to the State.
Monitor density for 50, 60 and 70 Series compaction using density gauges specified in §402-3.07E
Density Gauges. Ensure the density gauge operator possesses a current Density Gauge Inspector
Certification from The New York State Associated General Contractors, or its equivalent, as determined
by the Director, Materials Bureau. Any pavement section placed under 60 or 70 Series which is monitored
by a gauge operator whose certification is revoked for reasons outlined in the New York State Inspector
Certification Program Manual under “Decertification”, will be evaluated by sampling and testing of
pavement cores in accordance with §402-3.08 Pavement Density Samples, and subject to pavement density
adjustment. The above requirement also applies when a density gauge is used for monitoring pavement
density in the areas other than mainline under 50 Series compaction method.
Table 402-4 Compaction Methods associates specific item being placed to the required compaction
method.

A. 50 Series Compaction Method. On the first day of mainline paving, place and compact the
HMA mixture in accordance with the provisions of Option 1 or Option 2. Routine paving is the
placement and compaction of HMA mixture after the test section or first day paving.
1. Option 1 (Test Section). Place and compact a test section on the mainline a maximum of 1,500
feet long, at a location approved by the Engineer to determine if the HMA mixture can be
compacted uniformly within the 92-97% of MMTD. Ensure the thickness of the test section is the
same as the course it represents. Use the first 150 feet of the test section to stabilize the paving
operation. Once the test section is complete, the Engineer will select and mark 4 pavement core
locations, excluding the first 150 feet, in accordance with §402-3.08 Pavement Density Samples.
Extract pavement cores at the marked locations before the road is open to traffic. Take loose
mix samples as specified under §402-3.08. Deliver all the samples to the Regional Materials
Laboratory for testing and analysis. The following will apply to the test section.
• Place only one test section per day. Subsequent test sections are subject to approval by the
Engineer.
• Test Section Adjustment will apply for up to 200 tons placed on each test section.
• A maximum of two test sections per item will be subject to the Test Section Adjustment.
• The Test Section Adjustment will not apply for a test section if any HMA mixture of 150 tons
or more is placed on the same day, other than the quantity required for the construction of the
test section or permeable base placed under the test section location.
• Pavement Density Quality Adjustment will not apply to the first two test sections. Subsequent
test section(s) located on the mainline are subject to Pavement Density Quality Adjustment.
• Do not place HMA mixture under Routine Paving until the results of the pavement cores
from the test section have a minimum pavement density QAF of 1.00.
• If the pavement density QAF is less than 1.00, construct another test section.
• If the calculated QAF is 0.60, the Test Section Adjustment will not apply and the RME will
evaluate the test section in accordance with §402-3.14 Pavement Evaluation to determine if it
can be left in place.
2. Option 2 (First Day Routine Paving). Do not construct a test section on the first day of paving.
The Test Section Adjustment will not apply. All material placed and compacted will be subject to
a Pavement Density Quality Adjustment in accordance with Routine Paving, below. If the
pavement density QAF on the first day of paving is less than 1.00, construct a test section in
accordance with Option 1.
136 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
3. Routine Paving. A paving lot is defined as a day’s production of at least 200 tons. Each
paving lot will be equally divided into sublots in accordance with Materials Procedure (MP) 402-
02 Hot Mix Asphalt (HMA) Pavement Density Determination, based on the quantity placed.
When the quantity placed is less than 200 tons in a day, pavement samples are not required.
The density QAF for that day will be 1.00 provided the procedures used in these areas to obtain
pavement densities are similar to previously placed pavement sections based on the density gauge
test data.
When the quantity placed is more than 200 tons but less than or equal to 2000 tons in a day,
the Engineer will divide the lot into 4 equal sublots.
When the quantity exceeds 2000 tons, the Engineer will select one additional pavement core
location for up to every 500 tons over 2000 tons, up to a maximum number of cores for a lot of 8.
The Engineer will select and mark a pavement core location in each sublot in accordance with
§402-3.08 once the compaction operation is completed, excluding the first 150 feet of the day’s
paving.
Extract pavement cores at the marked locations in each sublot before the road is open to traffic,
fill the pavement core holes, take loose mix samples representing the lot, and deliver the sealed
pavement cores and loose mix samples to the Regional Materials Laboratory in accordance with
§402-3.08 Pavement Density Samples. The Department will test samples and analyze the results
within one work day of the delivery of the samples. The results of this analysis will be used to
determine the pavement density QAF in accordance with MP 402-02. When HMA mixture
placement is less than the anticipated quantities, obtain a minimum of two loose mix samples before
placement is terminated.
When paving over extended time periods using multiple crews, a new lot will be established
when a change in the paving crew occurs. When the work includes multiple paving operations,
each paving operation will be considered a lot and evaluated separately.
When two consecutive lots are found to have a density QAF equal to or less than 0.85, stop
paving operations and construct a new test section in accordance with Option 1.
Monitor density on the material placed on shoulders, widening, crossovers, bridges and ramps
with a uniform full-width section of less than 1250 feet in length using the same density gauge(s)
and target density used on the mainline. Record the density values on appropriate BR form based
on the type of gauge used, in accordance with MP 402-02. If the shoulder subbase is structurally
insufficient to sustain the level of compaction such that the shoulder shows signs of distress during
compaction, decrease the compaction effort until no further damage occurs to the shoulder or
subbase.
B. 60 Series Compaction Method. On the first day of mainline paving, place and compact the
pavement under the provisions of Option 1 or Option 2. Routine paving is the placement and
compaction of HMA mixture after Option 1 or after Option 2. Do not place HMA mixture under this
method unless both a density gauge and a certified operator are present.
1. Option 1 (Test Section Only). Place and compact a test section on the mainline a maximum of
1,500 feet long, at a location approved by the Engineer to determine a Project Target Density (PTD)
using the correlation of a density gauge(s) to the pavement cores results and to determine if the
mixture can be compacted uniformly within the 92-97% of MMTD. Use the same equipment and
procedures to construct the test section that will be used in the construction of the remainder of the
course being laid. Ensure the thickness of the test section is the same as the course it represents.
Use the first 150 feet of the test section to stabilize the paving operation. Once the test section is
complete, the Engineer will select and mark 4 pavement core locations, excluding the first 150 feet,
in accordance with §402-3.08 Pavement Density Samples.
Take density gauge readings in accordance with MP 402-02 at each pavement core location
prior to extracting pavement cores based on the type of density gauge used. Provide the density
137 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
gauge readings with the gauge type, model, and serial number to the Regional Materials Laboratory
in accordance with §402-3.08 Pavement Density Samples on Form BR 109.
Extract pavement cores at the marked location in each sublot before the road is open to traffic,
fill the core holes, take loose mix samples representing the lot, and deliver density gauge readings,
sealed pavement cores and loose mix samples to the Regional Materials Laboratory in accordance
with §402-3.08 Pavement Density Samples.
The Department will test the samples and analyze the results within one work day of the
delivery of the samples and density gauge readings. The results of the analysis will be used to
establish a PTD for each density gauge in accordance with MP 402-02. The following will apply
to the test section.
• Place only one test section per day. Subsequent test sections are subject to approval by the
Engineer.
• Test Section Adjustment applies for up to 200 tons placed on each test section.
• A maximum of two test sections per item will be subject to the Test Section Adjustment.
• The Test Section Adjustment will not apply for a test section if any HMA mixture of 150 tons
or more is placed on the same day, other than the quantity required for the construction of the
test section or permeable base placed under the test section location.
• If the average density of the four pavement cores results in a QAF of 0.60, the Test Section
Adjustment will not apply and the RME will evaluate the test section in accordance with
§402-3.14 Pavement Evaluation to determine if it should be left in place.
2. Option 2 (Test Section and Continue Paving). Place and compact a test section as described
under Option 1 on the mainline a maximum of 1,500 feet long, at a location approved by the
Engineer to determine a Project Target Density (PTD) using the correlation of a density gauge(s)
to the pavement cores results and to determine if the mixture can be compacted uniformly within
the 92-97% of MMTD. Use the same equipment and procedures to construct the test section that
will be used in the construction of the remainder of the course being laid. Ensure the thickness of
the test section is the same as the course it represents. Use the first 150 feet of the test section to
stabilize the paving operation. Once the test section is complete, the Engineer will select and mark
4 pavement core locations, excluding the first 150 feet, in accordance with §402-3.08 Pavement
Density Samples.
Take density gauge readings in accordance with MP 402-02 at each pavement core location
prior to extracting pavement cores based on the type of density gauge used. Provide the density
gauge readings with the gauge type, model, and serial number on Form BR 109, to the Regional
Materials Laboratory in accordance with §402-3.08 Pavement Density Samples.
Extract pavement cores at the marked locations in each sublot before the road is open to traffic,
fill the core holes, take loose mix samples representing the lot, and deliver sealed pavement cores
and samples to the Regional Materials Laboratory in accordance with §402-3.08 Pavement Density
Samples.
Establish an Interim PTD as described in MP 402-02 based on the density gauge used. Use the
Interim PTD to monitor pavement density until the Actual PTD is established by the RME. Prior
to the determination of an Actual PTD, take 4 additional loose mix samples, in accordance with
§402-3.08 and store these samples at the plant.
• The Test Section Adjustment factor will not apply.
• All material placed after the test section for that day will be subject to Pavement Density
Quality Adjustment.
Take density gauge readings at every 200 feet along the length of the pavement for each paver
pass, at locations randomly selected and marked by the Engineer, in accordance with MP 402-02.
138 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
If the density readings at two consecutive locations fall below 96% or above 103% of the
Interim PTD or if the moving average of the last 10 density readings falls below 98% of the Interim
PTD, stop paving operations and wait for the Actual PTD.
Submit a copy of the appropriate BR form(s) at the end of the first day’s paving to the Engineer
as described in MP 402-02. If the moving average of the last 10 density readings is below 98% of
the Actual PTD, the Engineer will randomly select and mark 4 pavement core locations in
accordance with §402-3.08 over the day’s placement under Interim PTD, excluding the test section.
Take density gauge readings in accordance with MP 402-02 at each pavement core location
prior to extracting pavement cores based on the type of density gauge used. Provide the density
gauge readings with the gauge type, model, and serial number on Form BR 109, to the Regional
Materials Laboratory in accordance with §402-3.08 Pavement Density Samples.
Extract pavement cores at the marked locations in each sublot before the road is open to traffic,
fill the core holes, take loose mix samples representing the lot, and deliver sealed pavement cores
and samples to the Regional Materials laboratory in accordance with §402-3.08 Pavement Density
Samples.
The Department will test the samples and analyze the results within one work day of the
delivery of the samples and density gauge readings. The results of the analysis will be used to
establish a PTD for each density gauge in accordance with MP 402-02.
If the average density of the pavement cores is not between 92% and 97% of the MMTD, the
Engineer will apply Pavement Density Quality Adjustment to the material placed under Interim
PTD, excluding the material placed on the test section.
3. Routine Paving. Do not place HMA mixture under Routine Paving until a PTD has been
established. Use only density gauge(s) that have been correlated with pavement cores during the
construction of the test section and a PTD has been determined by the Regional Materials Engineer.
For other gauge(s), construct a new test section under the provisions of “Test Section” to establish
a PTD. Compact the pavement sufficiently to achieve the PTD value at each test location. Take
density gauge readings at every 200 feet along the length of the pavement for each paver pass, at
locations randomly selected by the Engineer, in accordance with MP 402-02. Record density values
on the appropriate BR form based on the type of gauge used. Ensure the minimum density reading
is at least 96% and no greater than 103% of the PTD at a single test location and 98% of the PTD
calculated as a moving average of the last 10 test locations.
If density gauge readings over two consecutive locations fall below 96% or above 103% of the
PTD or if the moving average of the last 10 density gauge readings falls below 98% of the PTD,
stop routine paving operations and construct a new test section.
Monitor the density on shoulders, ramps, widening and crossovers with the same density gauge
to ensure the PTD is achieved. Use the appropriate BR form based on the gauge used to record the
density readings in accordance with MP 402-02. If the shoulder subbase is structurally insufficient
to sustain the level of compaction such that the shoulder shows signs of distress, decrease the
compaction effort until no further damage occurs to the shoulder or subbase.
When HMA mixture placement is less than the anticipated quantities, obtain a minimum of two
loose mix samples before placement is terminated. Before extracting the pavement cores, take
density gauge readings and record on Form BR 109. Deliver the sealed pavement cores, loose mix
samples, and the density gauge readings to the Regional Materials Laboratory for testing.
In addition to the daily density monitoring with a gauge, the Engineer will select and mark 4
pavement core locations every 3rd day of HMA mixture placement on the mainline from that day’s
placement for pavement density verification. Extract a set of pavement cores and loose mix samples
in accordance with §402-3.08, Pavement Density Samples.
The RME will calculate the PTD based on additional pavement cores taken every 3rd day of
HMA mixture placement for pavement density verification. If the calculated PTD differs from the
previous PTD by more than 2 lbs/ft3, the Engineer will establish a new PTD.
139 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
If the average density of the pavement cores is not between 92% and 97% of the MMTD, the
Engineer will apply Pavement Density Quality Adjustment to the material placed on day.
a. Provide additional pavement samples to verify pavement density of HMA placed under the
following situations:
• Insufficient number of density readings recorded, either at a specific location or at the
required frequency.
• Paving completed after the only correlated density gauge on site breaks down.
• Gauge readings do not seem to accurately represent the HMA density.
• Plant production QAF is 0.85 and need to evaluate the pavement section in accordance
with §401-4.10 Evaluation of Sublots Represented by 0.85 QAF, to determine whether
to keep it in place.
The Engineer will select and mark 4 pavement core locations in accordance with
§402-3.08 Pavement Density Samples.
Take density gauge(s) readings in accordance with MP 402-02 at each pavement core
location prior to extracting pavement cores based on the type of density gauge used.
Provide the density gauge readings with the gauge type, model, and serial number to the
Regional Materials Laboratory in accordance with §402-3.08 Pavement Density Samples
on Form BR 109.
Extract a pavement core at the marked location in each sublot before the road is open
to traffic, fill the core holes, take loose mix samples representing the lot, and deliver
sealed pavement cores and samples to the Regional Materials laboratory in accordance
with §402-3.08 Pavement Density Samples.
The RME will establish a new PTD based on these pavement cores. If the average
density of the pavement cores is not between 92% and 97% of the MMTD, the Engineer
will apply Pavement Density Quality Adjustment to the material placed under these
situations.
b. Provide additional pavement samples to verify PTD used for the situations listed below.
The material placed under these situations will not be subject to Pavement Density Quality
Adjustment.
• Changes in condition of existing pavement being overlaid.
• Excessive plant mixture variations.
• Using a different Job Mix Formula or a different HMA plant other than the one used
to produce mixture for the test section, as long as the aggregate and PG Binder sources
do not change.
4. Multiple Paving Sites. When the work includes multiple paving sites, construct a test section at
the initial paving site to establish a PTD. For the rest of the paving sites, provide pavement cores,
loose mix samples, and gauge readings on the first day to verify PTD.
The Engineer will direct that a test section be constructed if a different HMA plant other than
the one used at previous site(s) is supplying the HMA mixture using different aggregate and PG
Binder sources. The Test Section Adjustment will apply.
When a contract includes multiple sites, the requirement of additional set of pavement cores
applies to each paving site.
C. 70 Series Compaction Method. Place and compact HMA mixture in accordance with the contract
documents. Do not place HMA mixture, including the construction of the test section, unless both a
density gauge and a certified operator are present.
140 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
1. Test Section. On the first day of paving, place and compact a test section on the mainline, a
maximum of 1,500 feet long in one lane, at a location approved by the Engineer using the same
equipment and procedures to be used in the construction of the remainder of the course, to
determine the Project Target Density (PTD) using the “peak” method. Ensure the thickness of the
test section is the same as the course it represents. Use the first 150 feet of the test section to
stabilize the paving operation. Initially, compact the pavement with a breakdown roller once
sufficient HMA mixture is placed in the testable area. Select three random locations in accordance
with MP 402-02 based on the type of density gauge used and mark these sites so that subsequent
density testing can be performed at the same locations. Make necessary vibratory and static passes
to “peak” the pavement density such that the density gauge reading is within 92-97% of the MMTD.
Take density readings at the three selected sites after every additional machine pass until a “peak”
density is achieved. A “peak” density is achieved when the increase in density is less than 2 lbs/ft3
with compaction at 175ºF or less. Stop further compaction if the pavement shows signs of distress.
Determine the PTD by calculating the average of the highest density reading from each of the
random locations. Use the calculated PTD to monitor the pavement density. The Engineer may
request pavement cores to verify the PTD in accordance with MP 402-02.
Routine paving operations may begin after construction of the test section, and after a PTD has
been established and been verified by the Engineer based on the evaluation of density readings.
2. Routine Paving. Use only the density gauge(s) that were correlated during the construction of
the test section and its corresponding PTD to monitor pavement density during routine paving
operations.
Begin routine paving after the PTD has been established. Compact the pavement sufficiently
to achieve the PTD value at each test location. Ensure the minimum density reading is at least 96%
and no greater than 103% of the PTD in a single test location and 98% of the PTD calculated as a
moving average of the last 10 test locations, as determined by a density gauge. Take density gauge
readings at every 200 feet along the length of the pavement for each paver pass, at locations
randomly selected by the Engineer, in accordance with the MP 402-02. Record these values on the
appropriate BR form based on the type of gauge used.
If density gauge readings over two consecutive locations fall below 96% or above 103% of the
PTD or if the moving average of the last 10 density gauge readings falls below 98% of the PTD,
stop routine paving operations and construct a new test section.
Monitor density on shoulders, ramps, widening and crossovers with the same density gauge to
ensure the PTD is achieved. Use the appropriate BR form based on the gauge used to record the
density readings in accordance with MP 402-02. If the shoulder subbase is structurally insufficient
to sustain the level of compaction such that they show signs of distress, decrease the compaction
effort until no damage occurs to the shoulder or subbase.
The Engineer may request pavement samples for density verification of HMA placed under the
following situations at no additional cost to the State.
• Insufficient number of density readings recorded, either at a specific location or at the
required frequency.
• Paving completed after the only correlated density gauge on site breaks down.
• Gauge readings do not seem to accurately represent the HMA density.
D. 80 Series Compaction Method. Place and compact HMA mixture using either a static compaction
or vibratory compaction method.
The number of passes listed in Table 402-6 Number of Passes, are recommended and may be
increased or decreased by the Engineer to obtain adequate density. One vibratory pass is defined as one
movement of a single drum of the roller over the pavement section in each direction. One static pass is
defined as one movement of the roller over the pavement in each direction. Complete all breakdown
141 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
roller passes before the mat temperature falls below 250°F. Remove all ruts, ridges, roller marks, or
other irregularities from the surface using static rolling. Perform all turning of the rollers on material
which has had a minimum of one roller pass. The Engineer may approve alternate compaction
procedures for areas where the specified procedures are not applicable. Oscillatory rollers may be used
for either rolling option.

1. Based on 12-foot lane width.
2. For the Permeable Base course, compact the mixture between 140°F and 230°F. Up to 2
additional passes may be required to obtain adequate density.
1. Static Compaction. Use static compaction only when the compacted thickness of the finished
mat is 4 inches or less. Compact the HMA mixture using a 3 static roller train. Ensure the rollers
move at a uniform speed and do not exceed 3 mph. Ensure the roller drive wheel or drum is nearest
to the paver. When paving multiple lanes simultaneously, increase the required number of rollers
proportionately for each additional full lane width unless otherwise approved by the Engineer.
Compact the HMA mixture with steel-wheel rollers operating in a static mode. Ensure each pass
overlaps the previous roller pass by one-half the width of the roller.
Compact the HMA mixture with a steel-wheel roller immediately followed with a pneumatic
rubber-tired roller. Make a minimum of 3 passes of the rubber-tired roller. One pass is defined as
one movement of the roller over any point of the pavement in either direction.
Use a steel-wheel roller for finish rolling the HMA mixture to remove all shallow ruts, ridges,
roller marks, and other irregularities from the surface.
When the compaction procedure fails to produce acceptable results, adjust the procedure to
obtain the desired results.
2. Vibratory Compaction. Furnish a vibrating reed tachometer for the exclusive use of the
Engineer. Provide a vibrating reed tachometer having a frequency range of 1,000 vpm to 4,000
vpm with a minimum reed interval of 50 vpm between 1,000 vpm and 2,000 vpm and a minimum
reed interval of 100 vpm between 2,000 vpm and 4,000 vpm.
Ensure the settings on the rollers produce a minimum of 12 impacts per foot during the
compaction process. Impacts are defined as the number of times a drum hits the pavement within
one foot of travel and are determined using the following formula:
𝐼𝑚𝑝𝑎𝑐𝑡𝑠 𝑝𝑒𝑟 𝑓𝑜𝑜𝑡 =𝑉𝑃𝑀
𝑆𝑝𝑒𝑒𝑑
VPM = Frequency of the roller (vibration per minute)
Speed = Speed of the roller (feet per minute)
142 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
If the impacts are less than the minimum, adjust the settings and/or the speed to meet the
minimum impacts requirement.
If satisfactory compaction is not obtained, or damage occurs to highway components and/or
adjacent property using vibratory compaction equipment, cease using the vibratory compaction
method and complete the work using static compaction methods in accordance with 1. Static
Compaction at no additional cost to the State.
If number of roller passes, the roller setup, or minimum impacts per foot is not being met, stop
the paving operation, adjust the process as necessary, and restart the operation with the approval of
the Engineer.
E. Density Gauges. Provide density gauge(s) to monitor pavement density in accordance with
MP 402-02.
1. Nuclear Density Gauge. Submit a Safety Control plan at least two weeks prior to using the
gauge. Provide nuclear density gauge meeting the following requirements:
• Consist of a radioactive source, scaler, and other basic components housed in a single
backscatter unit.
• Calibrated at least every two years.
• Operated by personnel trained in the principles of nuclear testing and safety practices.
2. Non-nuclear Density Gauge. Provide non-nuclear density gauge meeting the following
requirements:
• Capable of functioning in the temperature and moisture levels experienced during HMA
mixture paving.
• Capable of determining the density of HMA pavements by measuring changes in the
electromagnetic field resulting from the HMA compaction process.
• Calibrated at least every two years.
402-3.08 Pavement Density Samples
A. Pavement Cores. The Engineer will select one pavement core location for each sublot in accordance
with MP 402-02. Take 6 inch diameter pavement cores from within the 10-inch diameter circles
outlined by the Engineer. The Engineer will not designate pavement core locations before the rolling
operation is completed, and all compaction equipment has moved off the sublot designated for coring.
Notify the Engineer immediately if a pavement core is in a location that is believed to not represent the
sublot. Extract the pavement cores no later than the end of the following day’s placement. If necessary,
cool the pavement so that the core samples are not damaged during coring. Do not separate the core
sample from the underlying layers if the pavement core sample does not de-bond during coring. The
Regional Materials Laboratory will separate the pavement core layer required for testing from the
underlying material by sawing, if necessary.
Extraction of companion cores is not allowed except for the following situations:
• As described in §402-3.08G Pavement Density Core Test Results
• To establish an Interim Project Target Density on the first day of paving. In that case, 2 cores
maybe taken during the construction of a test section
• To perform quality control tests during routine paving. A maximum of two cores are allowed
with prior permission of the Engineer. Do not take core(s) adjacent to the project cores.
B. Filling Core Holes. Fill all pavement core holes with a similar HMA mixture immediately after
extracting the cores or before opening the lane to traffic. Prior to backfilling, wipe the core hole with a
cloth to remove any standing water. Place HMA mixture in the core hole in layers of 3 inches or less
143 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
and compact each layer with 10-18 lb slide hammer with a diameter of at least 4 inches but less than 6
inches. Use of a shovel or similar method is not allowed. Use an alternative method approved by the
Engineer if it provides acceptable results. If core holes are not filled within 2 work days of placement,
the Engineer will stop routine paving until the core holes are filled.
C. Loose Mix Samples. On each paving day when pavement cores are required, take 4 loose mix
samples in accordance with AASHTO T168 Standard Test Method for Sampling Bituminous Paving
Mixtures. Take these samples such that they represent the day’s HMA mixture placement. The RME
may utilize loose mix maximum theoretical specific gravity values from plant HMA QC/QA testing.
When requested, supply the QCT and QAT results by e-mail or fax to the RME.
D. Securing Pavement Cores. The Engineer will secure and seal the pavement cores in accordance
with MP 402-02 once they have been extracted from the pavement.
E. Sample Delivery. Deliver the sealed cores, loose mix samples, and gauge density readings, when
required, to the Regional Materials Laboratory no later than the end of the following day’s placement.
Submit pavement cores, density gauge readings, and loose mix samples as required for 50, 60, or 70
Series methods together at the end of the day’s placement but no later than a day following placement
of the lot. If these samples are not submitted together for any paving lot, the QAF will be assigned a
1.00 or less for that lot when a QAF is applicable. If, for any reason, a delay occurs in the delivery of
the lot samples for three consecutive lots, stop paving operations until the samples are delivered and
tested.
F. Unacceptable Pavement Cores. Pavement cores damaged during extraction, pavement cores
delivered to the Regional Materials Laboratory for testing that are damaged, or pavement cores with
damaged or missing security seals will not be tested. The Engineer will select new pavement core
locations within a foot forward of the original locations at the same offset. Extract new pavement cores
from the newly identified locations.
G. Pavement Density Core Test Results. Upon receipt of test results of the pavement cores and loose
mix samples provided by the Regional Materials Laboratory, if the results are not representative of the
density gauge data or previous results for similar sublots, notify the Engineer and the Regional
Materials Engineer, in writing, within 2 work days. Include details as to what specific test results are
not representative, and the reasons, with the notification.
402-3.09 Joints. Ensure the finished pavement at all joints complies with the surface tolerance
requirements and exhibits the same uniformity of texture and compaction as other sections of the course.
Do not pass rollers over the unprotected edges of a freshly laid mixture unless approved by the Engineer.
Construct all joints, excluding the tapered wedge joint, such that the exposed edge of the newly placed
course is full thickness of the course and straight unless the exposed joint will not be part of the joint. If the
edge of the newly placed course is not straight or smoothly curved, correct the edge by using a power saw
or other approved tools to cut a neat line. Prior to placing the adjacent course, apply joint adhesive in
accordance with §402-3.06 Joint Adhesive, to all pavement edges in order to provide bonding with the
newly laid pavement.
Place successive HMA courses over an underlying course such that all longitudinal joints are offset no
more than 6 inches from the longitudinal joint of the lower pavement course, unless otherwise approved by
the Engineer. Place HMA courses on existing PCC pavement such that all longitudinal joints are stacked
on top of the joint of the underlying PCC pavement.
144 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
A. Transverse Joints. Place courses as continuously as possible to limit the number of transverse
joints. Stagger the transverse joints in adjacent lanes a minimum of 10 feet. Form the transverse joint
by cutting back the previous placement to expose the full depth of the course.
Set up the paver such that material laid overlaps the previously placed edge by 2 to 3 inches at a
thickness of approximately 25% of the compacted thickness of the course. Bump back the overlapped
material onto the adjacent hot mat using a rake so that the roller operator can crowd the material into
the hot side of the joint resulting in a smooth and well compacted joint after rolling. Do not broadcast
the overlap material onto the fresh mat. If the overlap is excessive, trim off the excess material so that
the material along the joint is uniform. Remove and discard the coarse particles of aggregate in the
overlap material if necessary.
Compact the transverse joint in static mode with the roller parallel to the joint and perpendicular to
traffic. Place boards of proper thickness at the edge of the pavement for the off pavement movement of
the roller. Make the first pass with the roller operating on the previously laid material with 6 to 8 inches
of its drum(s) overlapping onto the uncompacted HMA mixture. If a vibratory roller with pneumatic
drive wheels is used, align the first pass with one of the pneumatic wheels directly on the joint and the
drum operating in static mode. Make successive passes with the roller drum(s) moving approximately
one foot onto the hot material per pass until half the width of the roller is on the hot mat.
B. Longitudinal Joints. Ensure that the longitudinal joints in the Top Course will correspond with
the edges of the proposed traffic lanes. Other joint arrangements will require approval of the Engineer.
If a dual-drum vibratory roller is used during construction of a longitudinal joint using either Option
1 or 2, operate the roller in vibratory mode, unless static rolling is required. Operate rollers as close to
the paver as practical. Make the first pass with the roller traveling toward the paver and operating on
the hot mat with 6 to 8 inches of the roller drum overlapping onto the cold mat. Apply a second pass to
the joint as the roller travels back away from the paver.
If a single-drum vibratory roller with pneumatic drive wheels is used, operate the roller in vibratory
mode and follow the same procedure except that the roller will be aligned on the joint so that the
pneumatic drive wheels travels on the joint. Make all turning movements of the roller on previously
compacted material. After applying two roller passes on the longitudinal joint, proceed with the roller
to the low side of the lane and compact as described in §402-3.07 Compaction.
For all HMA courses other than Top Course, ensure no more than 100 feet of the longitudinal
pavement joint is exposed at the end of the working day when traffic is maintained on the roadway
during paving operations. For Top Course of 2 inches or less, refer to §402-3.09C Exposed Longitudinal
Joint.
When paving Top Course, construct the longitudinal joint using one of the options below. Use a
butt joint for all other HMA courses.
1. Option A - Butt Joint. Place the HMA mixture such that it uniformly overlaps the adjacent cold
mat 2 to 3 inches at a thickness of approximately 25% of the compacted thickness of the course.
Bump back the overlapped material onto the adjacent hot mat using a rake so that the roller operator
can crowd the material into the hot side of the joint resulting in a smooth and well compacted joint
after rolling. Do not broadcast the overlap material onto the fresh mat. If the overlap is excessive,
trim off the excess material so that the material along the joint is uniform. Remove and discard the
coarse particles of aggregate in the overlap material if necessary.
Bumping is not required when the use of a rake creates a safety hazard. Instead, place the HMA
mixture in a manner such that the thickness of the uncompacted course is approximately 25% more
than the compacted thickness of the adjacent HMA course with a ½ to 1 inch overlap.
2. Option B - Tapered Wedge Joint. Use this option when placing Top Course only. Place the
HMA mixture for the first mat with an attachment to the paver to provide a sloping wedge with a
vertical step-down at the longitudinal pavement joint. Extend a wedge of material from the bottom
145 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
of the step-down to the existing surface at a slope of 1 on 8 or flatter. The vertical step-down will
be ½ inch minimum after compaction of the mat. Place the second mat such that it uniformly
overlaps the adjacent cold mat 1 to 1 ½ inches at a thickness of approximately 25% of the
compacted thickness of the HMA course. Bump back the overlapped material onto the adjacent hot
mat using a rake so that the roller operator can crowd the material into the hot side of the joint
resulting in a smooth and well compacted joint after rolling. Do not broadcast the overlap material
onto the lane. If the overlap is excessive, trim off the excess material so that the material along the
joint is uniform. Remove and discard the coarse particles of aggregate in the overlap material if
necessary.
Bumping is not required when the use of a rake creates a safety hazard. Instead, place the HMA
mixture in a manner such that the thickness of the uncompacted course is approximately 25% more
than the compacted thickness of the adjacent HMA course with a ½ to 1 inch overlap.
C. Exposed Longitudinal Joint. Expose the longitudinal joint for the Top Course of up to 2 inches to
traffic for not more than 24 hours with the following conditions:
• Use Option B, Tapered Wedge Joint, except when the thickness is 1 inch or less where a butt joint
may be exposed to traffic.
• Place UNEVEN LANES (W8-11) warning signs posted in advance of the condition, at each
ramp, and roadway intersection, and repeated every ½ mile, supplemented with NEXT [X]
MILES (W16-4) auxiliary signs to alert drivers of the uneven edge.
• If the exposed longitudinal pavement joint becomes damaged due to rounding of the notched
wedge, saw-cut the joint prior to placing the adjacent lane.
• Apply joint adhesive to the exposed joint prior to placement of the adjacent lane in accordance
with §402-3.06 Joint Adhesive.
Do not allow exposed joints over the weekends, holidays, or when there are other concerns, such
as pending wet weather.
402-3.10 Surface Tolerance. Construct each pavement course to a ¼ inch surface tolerance. The Engineer
may test the surface with a 16-foot straight edge or string line placed parallel to the centerline of the
pavement and with a 10-foot straight edge or string line placed transversely to the centerline of the pavement
on any portion of the pavement. Variations exceeding ¼ inch will be appropriately corrected or the
pavement be removed and replaced at no additional cost to the State.
402-3.11 Thickness Tolerance. Construct the pavement so that the final compacted thickness is as near to
the nominal thickness as is practical, and within the tolerances specified below. The thickness indicated for
each of the various courses of HMA pavement is the nominal thickness.
The Engineer may request pavement cores to determine the thickness of the completed pavement course
for final acceptance and payment. Provide work zone traffic control and take pavement cores in accordance

with §402-3.08 Pavement Density Sample, at no additional cost to the State. The Engineer may use another
acceptance method such as yield calculations to determine the final thickness for acceptance and payment.
HMA mixture placed as a Truing and Leveling course as described in §402-3.05 Conditioning of
Existing Surface, will not be considered in pavement thickness determinations. The allowable tolerance for
HMA mixture specified under a single pay item is as follows:
• 1/4 inch or less for a required course whose nominal thickness is 4 inches or less
• 1/2 inch or less for a course or courses whose nominal thickness is over 4 inches
The tolerance for the total thickness of all HMA mixture courses is as follows:
• 1/4 inch or less when the total nominal thickness indicated on the plans is 4 inches or less
• 1/2 inch or less when the total nominal thickness is over 4 inches but not more than 8 inches
• 5/8 inch or less when the total nominal thickness is more than 8 inches
When the HMA mixture is placed on newly constructed subbase material, an additional tolerance of
1/4 inch will be allowed both in the nominal thickness of the course placed directly on the subbase and the
total pavement thickness.
No payment will be made for any material placed in excess of the permissible tolerance. Tolerances
indicated for the thicknesses of individual courses of multi course pavements (including composite
pavements) are guides which should be met as closely as practical. Tolerance for the total thickness of such
pavement is also a guide.
The HMA mixture placed may be accepted under the following conditions:
• When the individual course placed does not meet the thickness tolerance but substantially conforms
to the plans and specifications, true to line and grade in order to attain a smooth riding pavement.
• When the total thickness of such pavements is less than the specified thickness including tolerances
but substantially conforms to the plans and specifications.
• When the total thickness of such pavements is greater than the specified thickness and the excess
thickness is necessary to attain a smooth riding pavement surface.
Payment for excess thickness necessary to achieve a smooth riding surface will be considered only in
cases where an existing pavement surface has been resurfaced.
402-3.12 Paver and Equipment Cleaning. Do not clean tools and equipment used for HMA placement
on the pavement surface, or near streams, ponds, drainage structures or other areas that are tributaries to
waterways. Use an area approved by the Engineer for cleaning all paving equipment and tools. If possible,
remove solid pieces of asphalt by scraping or other mechanical means prior to application of a cleaning
agent. If a petroleum product is used for cleaning, contain all liquid products during cleaning operations
using tarpaulins, sand pads, pails, or other collection methods to prevent spillage or accidental release. Use
hand sprayers or other similar devices to minimize the amount of petroleum product applied. Properly
dispose of sand and collected petroleum products as petroleum contaminated soil at no additional cost to
the State.
402-3.13 Shoulder Edge Wedge. When specified, construct a shoulder edge wedge as detailed in the
contract documents. Place HMA mixture on the pavement shoulders where the outside edge of Top and
Binder Course consist of an angle of 35° or flatter measured from finished grade to the preceding course
surface. Construct the shoulder edge wedge by using a device attached to the screed. Minimize hand work.
Begin the top of the tapered section at the end of the shoulder width such that the tapered section will be an
additional width of material outside of the paved shoulder width. The shoulder edge wedge is optional at
locations where guiderails are installed.
147 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
402-3.14 Pavement Evaluation. The Regional Materials Engineer (RME) will evaluate mixtures either
placed or produced outside the specification limits which resulted in low quality adjustment factors.
A. Plant Production. When plant production QAF is 0.85, the RME will evaluate the pavement section
in accordance with §401-3.10 Evaluation of Sublots Represented by 0.85 QAF, whether to keep it in
place.
B. Pavement Density. When a QAF of a paving lot for 50 Series or 60 Series compaction is calculated
to be 0.60, the RME will evaluate the lot to determine if it can be left in place. The type of material
produced (i.e. Binder, Top), the course in which it is used, and the location of use (i.e., mainline or a
non-critical area) will be primary considerations in the determination of whether the HMA mixture can
be left in place. If the RME determines that the HMA mixture can be left in place, the Engineer will
apply a QAF of 0.60. If the HMA mixture cannot be left in place, remove and replace at no additional
cost to the State.
402-4 METHOD OF MEASUREMENT
402-4.01 Hot Mix Asphalt. The quantity of HMA mixture to be measured for payment will be in tons
placed to the nearest 0.01 tons.
402-4.02 Plant Production Quality Adjustment. Plant Production Quality Adjustments will be measured
in Quality Units determined for each day’s production using the daily Quality Adjustment Factor (QAF)
for plant production, determined in accordance with §401-3.07 Documentation. Quality Units for plant
production quality adjustments will be calculated using the formula below.
Quality Units = (Quality Adjustment Factor - 1.00) x HMA Placed (Tons)
402-4.03 Pavement Density Quality Adjustment. Pavement Density Quality Adjustments will be
measured in Quality Units determined for each day’s production using the daily Quality Adjustment Factor
(QAF) for pavement density. The quantity of HMA mixture subject to adjustment will be determined from
quantity placed on the mainline and ramps of uniform width longer than 1250 feet. When shoulders and
mainline are placed together, the mainline quantity may be determined using typical sections shown in the
contract documents.
The pavement density QAF will not apply to HMA mixture placed on ramps with a uniform full width
section less than 1250 feet in length, shoulders, widening, crossovers, and bridges. Payment in these areas
will be a QAF of 1.00 based on satisfactory placement and compaction.
Quality Units for pavement density quality adjustments under 50 and 60 Series compaction methods
will be calculated using the formula below. No pavement density quality adjustments will be made under
70 and 80 Series compaction methods.
Quality Units = (Quality Adjustment Factor - 1.00) x HMA Placed (Tons)
A. 50 Series Compaction QAF. The RME will determine the Percent Within Limits (PWL) for the
paving lot in accordance with MP 402-02 and determine the QAF as shown in Table 402-7 Quality
Adjustment Factors for 50 Series. The Engineer will use the QAF to calculate the Quality Units for the
accepted HMA mixture quantity.

is applicable, the Engineer will make the adjustment in accordance with Table 402-9 Quality
Adjustment Factors for 60 Series. A payment adjustment will be made, based on the Quality Unit Index
Price to all the material placed on the mainline for the day the pavement cores represent.

402-4.04 Test Section Adjustment. Test Section Adjustments will be measured in Quality Units using a
test section adjustment factor of 0.5 for up to the first 200 tons placed on a test section on the mainline.
Quality Units for Test Section Adjustment for 50 and 60 Series compaction methods will be calculated
using the formula below.
Quality Units = 0.5 x HMA Placed on Mainline (Tons)
402-5 BASIS OF PAYMENT. The unit price bid for all HMA mixture shall include the cost of all labor,
materials, and equipment necessary to satisfactorily complete the work, including extracting the pavement
cores, filling, and compaction of all core holes. Application of tack coat, joint adhesive, and cleaning will
be paid separately except when the joint adhesive is applied under §402-3.01E.
149 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2

161 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
411-3 CONSTRUCTION DETAILS
411-3.01 Placement. After the base has been brought to grade and cross section, as shown on the plans,
thoroughly compacted, and approved by the Engineer, the Contractor shall place the stabilized gravel
surface course.
When calcium or sodium chloride additives are specified, they shall be added by an approved
mechanical distributor after the gravel has been spread and prior to the addition of water. Calcium
chloride shall be added in the amount of 1/2 pound per square yard per inch of compacted thickness of the
course. Sodium chloride shall be added at a rate of 2 pounds per square yard per inch of compacted
thickness of the course which is equivalent to approximately 2% of sodium chloride based on dry weight
of aggregate. Water shall then be added to the material in amounts as directed by the Engineer.
If the Contractor so elects, only the calcium chloride may be added to the gravel material as a water
solution. In such cases the Contractor shall submit to the Engineer a detailed description in writing of the
proposed procedure of operations. Construction shall not be started until the Engineer`s approval is
obtained in writing.
411-3.02 Mixing

SECTION 417 – HOT MIX ASPHALT USING RECYCLING TREATMENTS (New Section January, 2017)
417-1 DESCRIPTION. This specification includes two processes for in-place recycling hot mix
asphalt pavements: heater scarification (HS) and hot-in-place recycling (HIPR). The HMA pavement
surface is heated using specialized equipment to soften the asphalt.
164 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
In the HS process, the softened HMA surface is scarified to a specified depth as detailed in the contract
documents. The scarified asphalt pavement is then mixed with a recycling agent that rejuvenates the asphalt.
This mix is then placed and compacted back onto the roadway. The scarified layer must be overlaid.
In the case of the HIPR, the multi-step recycling process of the existing pavement includes heating,
milling, and adding a recycling agent to rejuvenate the asphalt; then mixing, placing, and compacting the
mixture. The resulting recycled pavement does not require an overlay. If the contract documents require
the addition of virgin HMA 19.0 mix during the HIPR process, then the resulting pavement will require an
overlay.
417-2 MATERIALS
417-2.01 Recycling Agent. Use a recycling agent specifically designed as a rejuvenator meeting
the requirements outlined in Section 702 – Bituminous Materials, 8. Asphalt Recycling Agent, Table 702-9
Recycling Agent or Table 702-10 Emulsified Recycling Agent. At the start of and during production, provide
certified test results and documented quantities to the Engineer for each shipment of recycling agent. The
use of any other grade of recycling agent or other product requires prior approval from the Director,
Materials Bureau. A minimum 2-week notice is needed for this approval. 417-2.02 Mixture Design. Determine the application rate of the recycling agent for heater
scarification and hot in-place recycling by taking and analyzing a minimum of three cores per lane mile or
a maximum of 20 cores per project from the existing HMA pavement. Take these cores from locations that
represent the entire project condition.
Make sure that the designed application rate of the recycling agent provides the average penetration
value of the recovered asphalt binder from the loose mix samples, taken during both the HS and HIPR
process, to have an increase of at least 30% or more than the average penetration value of the recovered
asphalt binder from the existing pavement cores. Do not exceed the final penetration value of 90. Perform
all the sample tests for the penetration values in accordance with AASHTO T 49, Penetration of Bituminous
Materials.
417-2.03 Virgin Hot Mix Asphalt. When specified in the contract documents, add virgin 19.0 HMA
binder mix to the Hot-In-Place Recycling mixture. Provide virgin HMA meeting the requirements outlined
in Section 402 – Hot Mix Asphalt (HMA) Pavements. The contract proposal will include the performance-
graded (PG) binder, mix type, mix design level, and rate of virgin HMA. Do not use RAP in the virgin
HMA mix.
417-3 CONSTRUCTION DETAILS. §401-3 and §402-3, Construction Details, apply, except as
modified below:
417-3.01 General
A. Pavement Markings. Remove all epoxy or thermoplastic pavement markings, and other markings
when ordered by the Engineer. B. Cleaning. Clean the existing pavement and shoulder to be heater scarified or hot in-place recycled
by using mechanical sweepers, or other effective means until the surface is free of all debris material,
which might interfere with the scarification or milling process.
C. Calibration for Spray Unit and Recycling Injection System. Calibrate the metering system in
accordance with NYSDOT’s Materials Procedure (MP) 417-01 - Calibration of Metering System for
Recycling Equipment. Other calibration methods may be used with the approval of the Engineer. A
minimum 2-week notice is required when scheduling this calibration. Perform the calibration of the
metering system in the presence of the Regional Materials Engineer or designee. Work shall not
165 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
progress until the calibration has been completed and verified. Each project requires an approved
calibration. Approved calibrations are valid for 90 days and may be used for more than one project. If
the calibration date exceeds 90 days, then recalibrate the metering system.
417-3.02 Heater Scarification (HS).
A. Heater Scarification Train. The heater scarification train consists of at least two heating units
and a heater scarification unit consisting of a scarifier, a sprayer, a milling/remixer drum, and a screed.
1. Preheating or Heating Unit. This unit must generate sufficient radiant heat with no open
flame to soften the asphalt pavement to the depth required. The burner assembly must be adjustable
to heat between 8 and 14 feet in width. The entire heating unit must be enclosed and vented to
contain the heat and prevent damage to adjacent properties and landscape. Additional heating units
may be required if the temperature behind the screed does not meet specification requirements.
2. Heater Scarification Unit. This equipment must be a self-contained machine designed to
reprocess only the upper layers of the existing HMA pavement. The heater scarification unit must
be self-propelled and capable of operating at speeds of 8 to 26 feet per minute while uniformly
heating and scarifying the existing HMA pavement to the minimum loose mix depth specified in
the contract documents. Listed below are the various units that are part of the heater scarification
train.
a. Scarifier. The scarifying unit must contain at least 2 rows of spring-loaded tines that are
adjustable to scarify 8 to 14 feet wide. The tines in a row must be no more than 1.0 inch apart.
This unit must also be able to conform to the pavement contours to ensure a uniform penetration
from the tines and prevent damage to utility structures.
b. Sprayer. This unit must be immediately behind the scarifying unit and capable of
uniformly applying the recycling agent to the reclaimed asphalt pavement at the approved rate.
Select the size of the nozzles located on the spray bar and pump based upon the rate of
application and the forward speed of the heater scarification unit. This unit must be equipped
with a measuring system which is capable of maintaining the required application rate of the
recycling agent within a tolerance of ± 5% for the mix design. The measuring system must
continuously verify and display the application rate of recycling agent and cumulative total
with respect to the volume of scarified material for the road surface.
c. Mill/Remixer. Immediately following the application of the recycling agent, an enclosed
milling unit is required to mill the asphalt pavement to the loose mix depth specified in the
contract documents, thoroughly mixing the recycling agent with the scarified and milled
pavement. The mill/remixer unit is an integral part of the scarifying machine and must be
located between the spray unit, which applies the recycling agent, and the screed. This unit
must be operated hydraulically and able to work at variable speeds up to 120 rpm.
d. Screed. The attached heated, augured vibratory screed must be able to uniformly distribute
the hot scarified material to the desired longitudinal and transverse section. The screed must be
adjustable from 8 to 14 feet wide, equipped with an adjustable crown control and each end of
the screed must have hand wheel adjusting screws for providing the desired longitudinal grade
and transverse slope.
B. Mixture Verification and QC Testing.
166 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
1. First day: Prior to the scarification process, the Engineer will select two core locations on
the existing pavement. These locations will be within a lane mile or fraction thereof if production
is less than one mile. Extract two cores at each location and test one core from each location for
penetration of the extracted asphalt binder from the surface layer only. Provide the companion core
from each location to the Engineer for testing by the Department for verification purposes.
During the scarification process, take four loose mix samples prior to compaction at each
location where cores were taken. These samples will be representative of the day’s production.
Take samples either behind the screed or any place after the spraying and mixing units. Identify all
samples by their locations at the project site. Test two of the loose mix samples from each core
location for penetration and provide the other two loose mix samples to the Engineer, which may
be evaluated by the Department’s Lab to verify test results. Take all the required core and loose
mix samples after the first 500 feet of the day’s production.
Submit penetration test results to the Engineer by the end of the next day’s production. If test
results are not provided, the Engineer may shut down the scarification process until the results are
submitted. Determine the penetration of the PG binder recovered from the recycled mixture in
accordance with AASHTO T 49. The average penetration value of the loose mix samples must be
at least 30% or more than the penetration of the core samples taken from the existing pavement.
If the average penetration values of the loose mix samples fail to meet this requirement, adjust
the application rate and submit the new adjusted application rate to the Engineer. Repeat the
procedure described above for taking and testing samples. Submit the penetration test results to the
Engineer by end of the next day’s production. Continue adjusting the application rate and taking
samples until average penetration values of the loose mix samples meet the specification
requirement of at least 30% or more than the penetration values of the core samples.
2. Routine Day: If the specification requirements are met after the first day’s production, take
samples as described above every three days of production for quality control and quality assurance
purposes. Samples of the scarified pavement prior to rejuvenation can be taken as an option instead
of the core samples. When sample results do not meet the specification requirements, make
adjustment to the application rate and take samples as described above.
If, at anytime, the average penetration value of the loose mix samples is greater than 90, the
Engineer may evaluate the pavement section and request the scarified pavement be removed and
replaced at no additional cost to the State. The evaluation may include, but not limited to, testing
penetration of the core sample, location of the section, etc. If core samples are required for this
evaluation, take them at no additional cost to the State and submit them to the Department for testing.
Also, if the recycled pavement is not satisfactory to the Engineer, additional tests may be required at
no cost to the State.
C. Placement. Radiantly heat the existing HMA pavement surface with no open flame using
specialized equipment to soften the HMA surface and scarify to a specified depth as detailed in the
contract documents. Take care not to overheat the existing pavement thereby softening the underlying
asphalt pavement not to be milled or scarified and that burning of the existing asphalt cement does not
occur. Operate the heating unit(s) in a manner to prevent damage to adjacent property and vegetation.
Repair all heat-damaged areas immediately, at no additional cost to the State.
Control the heater scarification equipment to ensure the temperature of the scarified mixture is
maintained between 275ºF and 325ºF. Verify this temperature within 5 feet behind the screed unit.
Control the speed of the equipment to ensure that the recycled pavement is properly milled, mixed,
and uniformly distributed to the proper thickness, slope, and crown shown on the contract plans. Take
extra care in controlling heater scarification equipment to prevent segregation of the recycled mix at
the start and end of paving production as well as any points where the heater scarification train needs
167 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
to stop and restart. Control the width of each pass to provide proper placement of longitudinal joints,
including a 3-inch overlap onto adjacent lane passes.
Add recycling agent uniformly to the scarified HMA pavement at the predetermined application
rate to produce a homogenous HMA recycled mix.
Ensure that the final recycled pavement conforms to the requirements of §402-3.10, Surface
Tolerance and §402-3.11, Thickness Tolerance. Measure the depth of the loose scarified mix behind
the screed unit prior to the rolling operation. Adjust the paving equipment if the loose mix depth does
not provide the compacted depth specified in the contract documents.
In areas not accessible to scarifying equipment, such as around catch basins or manholes, the
Engineer will determine if they require repair. Pavement surfaces that are in good condition do not
require repair. Repair all areas with cracks or spalls, as approved by the Engineer, at no additional cost
to the State.
D. Compaction. Compact the recycled mixture in accordance with §402-3.07, D., 80 Series
Compaction Method.
E. Overlay. Once work is completed, overlay the recycled HMA pavement to the satisfaction of
the Engineer. Place the overlay prior to the end of the paving season. This work must be done under a
separate pay item in the contract documents.
417-3.03 Hot In-Place Recycling (HIPR).
A. Hot-In-Place Recycling Train. The HIPR train consists of a preheating unit, main recycling unit
consisting of a heating system, a hot milling unit, a recycling injection system, a blending unit/mixing
chamber, and a conventional paver. The equipment must be capable of processing the existing
pavement to a minimum depth of 2 inches. HIPR equipment approved for use will appear on the

418-3 CONSTRUCTION DETAILS
General. Furnish all equipment that is necessary to clean the construction joint and to apply the joint
adhesive. Use equipment meeting the description and/or performance requirements described herein and
approved by the Engineer. Apply the joint adhesive to the construction joints.
Joint Preparation. Prepare longitudinal and transverse construction joints as discussed below and place
adjacent asphalt pavement on the same day that the joint adhesive is applied.
Use a high pressure air lance to thoroughly clean the joint surface of dust, dirt, foreign material, sand
and any other extraneous materials immediately prior to applying the joint adhesive. Install suitable traps
or devices on the compressed air equipment to prevent moisture and oil from contaminating the joint
surfaces. Maintain these devices and see that they are functioning properly. Protect the public from
potentially objectionable and/or hazardous airborne debris.
Joint Adhesive. Heat and melt the joint adhesive in a melter constructed either as a double boiler filled
with a heat-transfer medium between the inner and outer shells, or with internal tubes or coils carrying joint
adhesive through a heated oil bath and into a heated double wall hopper. The melter will be equipped with
separate thermometers to indicate the temperature of the heat transfer medium and the joint adhesive
material, positive temperature controls, and with a mechanical agitator or a recirculation pump to assure a
homogeneous blend of the joint adhesive.
Check the discharge temperature of the joint adhesive with a non-contact infrared thermometer or other
suitable thermometer. Discharge the joint adhesive at the manufacturer's recommended application
temperature and maintain the joint adhesive at ± 10°F of the application temperature indicated on the
material packaging.
Applying joint adhesive is not permitted if the melter and discharge temperatures do not meet the
requirements described above.
Equip the discharge hose with a thermostatically controlled heating apparatus or insulate it to maintain
the proper joint adhesive application temperature. Holster the discharge hose to the melter if it is not
thermostatically heat controlled. Circulate the joint adhesive from the discharge hose and the melter to
maintain the proper joint adhesive application temperature.
Do not use joint adhesive material that has been heated beyond the safe heating temperature. If the
manufacturer's recommendations allow the joint adhesive to be reheated or heated in excess of six hours,
recharge the melter with fresh material amounting to at least 20 percent of the volume of the material
remaining in the melter.
Application. Apply the joint adhesive when surface temperature is 40°F and rising. Use an applicator wand
fitted with a sealing shoe to strike-off the adhesive. Strike-off the joint adhesive to provide a 1/4 inch to 3/8
inch thick band. The finished bands are to be approved by the Engineer.

B. Admixtures. Admixtures are used to achieve the desired set retardation, water reduction, slump,
air content, and to protect reinforcing steel from corrosion. Admixtures are not considered part of the
solid volume in the concrete mixture. The admixture manufacturer’s recommended maximum dosage
rate should not be exceeded to obtain the desired results as specified in Table 501-3.
1. Air Entrainment. Air entraining agent is required for all mixes to produce concrete with an air
content in the range specified in Table 501-3, Concrete Mixtures unless otherwise indicated in the
contract documents. The Engineer will test the concrete for plastic air content, and reject concrete
with air contents outside the specified limits.
2. Retardation. The setting time of concrete may be retarded when necessary for proper
placement. A water- reducing and retarding admixture (§711-08, ASTM Type D), is required in
Class DP for Structural Slab Overlays (Section 584), Class HP for Superstructure Slabs and
Structural Approach Slabs (Section 557), Class G and Class GG concrete. It may be used with, or
in place of, a water- reducing admixture (§711-08, ASTM Type A) in other applications that
allow Class DP or Class HP. Limit the use of the water- reducing and retarding admixture to the
minimum amount required to achieve retardation during placing conditions. Unless otherwise
specified, the use of water- reducing and retarding admixtures are subject to approval of the

NOTES :
1. Mixture proportions will be computed by the Regional Materials Engineer using the fineness modulus and bulk specific
gravities (saturated surface dry) of the aggregates proposed for use.
2. Class DP and HP require the replacement of portland cement with 20% pozzolan and 6% microsilica and the addition of a
water reducing admixture and / or water- reducing and retarding admixture. Refer to §501-3.01 B, Admixtures.
3. Class G and GG require the replacement of portland cement with 20% pozzolan, and the addition of a water- reducing and
retarding admixture. Refer to §501-3.01 B, Admixtures.
4. These mixes require the use of a water reducing admixture. Refer to §501-3.01 B, Admixtures.
5. T.C.M. = Total Cementitious Material.
6. Slump range for slipform paving is 1 – 2 1/2 inches and for fixed form paving is 1 1/2 – 3 inches.
501-3.02 Handling, Measuring and Batching Materials. Arrange the batching facility and equipment
to assure a continuous supply of material to the work.
When written approval is granted by the Director, Materials Bureau, bagged material may be
incorporated into the mix. Adjust the batch size to use whole bags of bagged material. The handling,
measuring and batching of bagged material must be verified and documented by a Department
representative.
A. Stockpiles. Build good draining bases for stockpiles, at the batching facility, on prepared
aggregate, concrete, metal or wood surfaces, or barge floors, subject to approval by the Regional
Director. Build the stockpiles by methods which do not cause particle segregation. Stockpile all
aggregates separately, by source and size so that no cross contamination occurs. Label all Department
approved stockpiles by source number.
Handle aggregates throughout the batching process such as to maintain uniform grading of the
material. In case the aggregates contain a high or non-uniform moisture content, stockpile the
aggregates for a sufficient length of time to stabilize the moisture content.
Equip each plant with a moisture sensing device that indicates, on a readily visible scale or chart,
the fine aggregate moisture content as it is batched. Indicate the free moisture content on the batch
recordation during batching. The free moisture content during batching is limited to a maximum of
8% of the fine aggregate’s saturated-surface dry weight.
189 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The Regional Materials Engineer will determine the acceptability and accuracy of the moisture
sensing device. If the device is considered accurate, the free moisture content of the fine aggregate
may be allowed to be adjusted between batches based on the most recent moisture reading. No
adjustment for free moisture will be allowed for an individual batch after batching starts.
B. Heating Materials for Cold Weather Concreting. Use equipment that uniformly heats the
materials. To obtain the specified temperature of the plastic concrete when the air temperature is
below 32°F, heat the aggregates by steam or dry heat and heat the mix water. When the air
temperature is 32°F or more, and the aggregates are free of ice, the specified temperature may be
obtained by heating only the mix water. The equipment and operations for heating the materials must
be approved by the Regional Director prior to use on Department projects.
Specified Temperature Range Minimum Maximum
Mix Water 70°F 180°F
Aggregate 40°F 100°F
Plastic Concrete in place 50°F 70°F
To avoid the possibility of flash set when water is heated over 100°F, combine the water and
aggregate in the mixer so that the water temperature is reduced before cement is added.
C. Batching.
1. Aggregates. When sizes are weighed cumulatively, allow a ±2% tolerance for each draw weight,
based on the combined aggregate batch weight. If sizes are weighed separately, apply the tolerance to
each scale weight.
2. Cement and Pozzolan.
a. Batching without microsilica or HRP added independently on a common scale. Weigh the cement,
blended cement, or pozzolan cumulatively with a ± 1% tolerance for each draw weight (based on the
combined weight of all cementitious materials). Weigh the pozzolan last in the weighing sequence.”
b. Batching with microsilica or HRP added independently on a common scale. Weigh all
cementitious materials cumulatively with a ± 0.5% tolerance for each draw weight (based on the
combined weight of all cementitious materials). Double the minimum allowable batch weight. Weigh
the microsilica or HRP last in the weighing sequence.
3. Microsilica and High Reactivity Pozzolan (HRP).
a. Batching with cement, Type IP or SM blended cement, or pozzolan on a common scale. Weigh the
microsilica or HRP cumulatively with a ± 0.5% tolerance for each draw weight (based on the
combined weight of all cementitious materials). Double the minimum allowable batch weight. Weigh
the microsilica or HRP last in the weighing sequence.
b. Batching microsilica or HRP on a separate scale. Weigh the microsilica or HRP with a ± 1%
tolerance (based on the total weight of microsilica or HRP.
D. Delivery Tickets. Each delivery ticket must contain the following:
• SiteManager Mix ID
• Delivery Ticket Number
• Plant Identification, with plant name and location and/ or facility number
• Contract Number
• Concrete Class or Item Number
190 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
• Quantity (Nominal Batch Size)
• Truck Number
• Batch Number

may consist of one of the following :
Time - Date stamp by separate printing device on a regular ticket
Time - Date printed by a batch weight recorder on a printed ticket.
Time - Date printed by a batch weight recorder on a printed tape. Affix a copy of the tape to
the regular delivery ticket.
E. Failure of Automatic Batching, Admixture Dispensing and Recording Equipment. If automatic
proportioning, admixture dispensing or recording instruments fail, the plant may be allowed, subject
to approval of the Regional Director or his representative, to continue producing concrete for the
Department for up to 48 hours from the time of breakdown. Written permission of the Regional
Director will be required to operate without these instruments for periods longer than 48 hours.
During this period, batch all materials within the automatic proportioning system tolerances.

Regional Director before evidence of initial set. No water addition will be permitted after the mix
has reached the mid-point of the slump range, as indicated in Table 501-3, Concrete Mixtures, for the
class used. Concrete with a discharge temperature exceeding 90°F will be subject to rejection.
Notify the Regional Materials Engineer’s office by 3:00 PM on the day before any production for
the Department. Supply fresh concrete at a rate consistent with placement operations as determined
191 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
by the Engineer. The Regional Director may disapprove the use of any type of concrete mixing or
transporting units when unsatisfactory results occur.
Load the mixer, regardless of type, in a manner approved by the Regional Director and mix
batches of concrete no larger than the rated capacity shown on the Manufacturer's plate.
A summary of time limitations for various types of concrete mixing equipment, from the
beginning of batching to the completion of discharge, is given in Table 501-7, Summary of Concrete
Batching, Mixing, Hauling and Discharging.
B. Concrete Uniformity. Use a mixer that combines aggregates, cementitious materials, water and
admixtures into a uniform weight within the specified time. The mixer is required to discharge the
mixture without segregation, and meet the uniformity requirements in Table 501-5, Concrete
Uniformity. The Department will perform tests when required by the specifications or requested by
the Regional Director.
It will only be necessary to verify that mixing equipment meets uniformity requirements if
evidence of non-uniform concrete is found or a reduced mixing time for central mixers is requested.
A reduction in the batch size below the rated mixer capacity or reduced mixing speed tolerance limits
may be required to obtain uniformity.

Unit weight of air-free mortars based on average for all
comparative samples tested 1.6 %
NOTE: The Department will take samples at the mixer discharge point and test in accordance with Materials Method 9.2.
C. Central Mixed Concrete. Central mixed concrete is concrete mixed in a stationary mixer and
transported in approved agitating or non-agitating delivery units to the deposition point. Use a
minimum 90 second mixing time after all materials are in the drum, unless tests show that the
requirements of Table 501-5, Concrete Uniformity, can be consistently obtained at a lesser time as
approved by the Director, Materials Bureau.
Use delivery units that transport thoroughly mixed concrete without loss of uniformity meeting
the requirements of §501-2.04B.1.b. or §501-2.04B.2., pertaining to Central Mixed Concrete.
Travel on a haul road free from holes, washboarding or other features that cause segregation in
plastic concrete.
Do not exceed the time limit between completion of mixing at a central mix plant and completion
of discharge as noted in Table 501-6, Time Limits for Delivery of Central Mixed Concrete.
When transporting central mixed concrete in units approved for truck mixing, add a minimum of
90% of the design water to the mix with the batch plant water system.
Two additions of water will be allowed at the discharge point to obtain initial slump. After each
addition, mix the concrete at least 30 mixing-speed revolutions before discharging. The initial loads
may, with prior written approval by the Regional Materials Engineer, also be adjusted by using a
water- reducing admixture (711-08, ASTM Type A). This adjustment will be limited to the first
192 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
trucks arriving for a particular placement before any adjustments have been made at the batching
facility. Observe the maximum number of mixing revolution or water addition requirements. Make
all subsequent admixture additions or adjustments during production at the batching facility. No
additions or adjustments are allowed when non-agitating / open haul units are used.

under unusual conditions if unsatisfactory results occur. For concrete that does not contain a water- reducing and retarding
admixture, the time to initial strike-off or placement of subsequent lifts is included in the delivery and discharge time limit.
D. Transit Mixed Concrete. Transit mixed concrete is concrete batched at the production facility and
mixed completely in a truck mixer at the following locations or combinations thereof: the plant, while
in transit, or the discharge point. Transit mix may be used for all concrete items unless otherwise
specified. Use a truck mixer meeting the requirements of §501-2.04B.1.a., pertaining to Transit
Mixed Concrete.
Load the mixer as follows:1. Totally drain the drum of wash water before loading.
2. Revolve the drum while loading the mix ingredients and add approximately 90% of the design
water.
3. Begin mixing within 5 minutes of cement to aggregate contact .

NOTES:
1. The remainder of the design water may be added at the work site to attain initial slump. When approved by the Regional
Materials Engineer, only the first trucks may be adjusted to obtain initial slump using a water-reducing admixture (711-08,
ASTM Type A). Exceeding the maximum mixing revolutions or water addition requirements will not be permitted.
2. For mixtures that do not contain a water-reducing and retarding admixture (711-08, ASTM Type D), the 90 minute
maximum time includes the time to initial strike- off, or placement of subsequent lifts.
3. Add cement through hatch. Do not move drum while cement is being added. Mix for a minimum of 100 mixing- speed revolutions and then check for consistency. If the truck
is en route to the project, change the speed from mixing to agitating after 100 mixing revolutions.
Unless restricted by local traffic laws, do not stop the rotation of the drum during transit.
Two additions of water will be allowed to obtain initial slump at the discharge location . After
each addition, mix at least 30 mixing speed revolutions. For Class DP or HP concrete, mix a total of
100 to 200 mixing speed revolutions. For all other classes of concrete, mix a total of 100 to 160
mixing speed revolutions.
The initial loads may, with prior written approval by the Regional Materials Engineer, also be
adjusted by using a water- reducing admixture (§711-08, ASTM Type A). This adjustment will be
limited to the first trucks arriving for a particular placement before any adjustments have been made
at the batching facility. Observe the maximum number of mixing revolution or water addition
requirements. Make all subsequent admixture additions or adjustments during production at the
batching facility.
After mixing, either discharge the load immediately or revolve the drum at agitating speed. Once
begun, discharge the entire load within 50 minutes.
For mixes containing a water- reducing and retarding admixture, the total time interval from the
moment the cement makes contact with the aggregates to the completion of discharge shall not
exceed 90 minutes.
For mixes that do not contain a water- reducing and retarding admixture, the total time interval
from the moment the cement makes contact with the aggregates to the completion of initial strike off
or placement of subsequent lifts shall not exceed 90 minutes.
The Regional Director may reduce the total time limit in hot weather or under unusual conditions,
if unsatisfactory results are obtained.
E. Truck Mixed Concrete. Truck mixed concrete is concrete completely mixed in a truck mixer
meeting the requirements of §501-2.04B.1.b. Truck Mixers, after adding water at the discharge
location. Apply §501-3.03D. Transit Mixed Concrete, except as follows:
1. Loading of Mixer:
a. Regular Truck Mix (cement in contact with moist aggregates). The drum may be rocked or
revolved while loading coarse and/or fine aggregates with admixtures. Load the cement last,
while keeping the drum stationary. Begin mixing within 30 minutes of cement to aggregate
contact.
194 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
b. Layered Truck Mix (cement in contact with Saturated Surface Dry(SSD) or drier coarse
aggregate). Batch the fine aggregate with admixtures, coarse aggregate and cement all
separately. Load these materials through a hatch in the side of the drum in the following
sequence: fine aggregate with admixtures, coarse aggregate, and cement last. The drum may
be rocked after adding each aggregate size, but kept stationary while loading the cement.
Begin mixing within 90 minutes of cement to coarse aggregate contact.
2. Mixing: Begin mixing at the discharge location. Add water to the drum either from the head
section or by dual injection from both the head and discharge end. Mix for a minimum 100
revolutions or until uniform concrete of the specified consistency is produced, whichever is
longer. Do not exceed a 15 minute mixing period.
3. Discharge: Discharge the entire load within 30 minutes after mixing.
501-4 METHOD OF MEASUREMENT. The Engineer will compute the volume of concrete as the
number of cubic yards within the payment lines indicated on the plans or as specified by the Engineer.
No deductions will be made for the volume of embedded reinforcement, structural shapes or joint
materials. Also, no deductions will be made in concrete pavement for catch basins, manholes, etc. unless
otherwise indicated in the contract documents.
501-5 BASIS OF PAYMENT. Include the cost of furnishing all materials, equipment and labor
necessary to complete the work in the unit price bid for the appropriate items.

If requested, provide the Engineer with any appropriate manufacturer’s details and/or instructions for
use of listed materials before use of the product.
In addition to meeting the requirements of §701-14, Chemically Curing Adhesive for Portland
Cement Concrete (PCC) Pavement Applications, the material used to anchor longitudinal joint ties,
dowels, or other miscellaneous items into hardened concrete must be a pourable, two-component, 100%
solid structural epoxy dispensed:
• From side-by-side cartridges by manual or pneumatically powered injection guns.
• Through a static mixing nozzle that homogeneously mixes the material without any hand mixing.
502-2.01 Concrete. Use Class C concrete furnished in accordance with Section 501, Portland Cement
Concrete – General, when specified. High-Early-Strength (HES) concrete, meeting the requirements of
§502-2.02, may be substituted for closure or short placements, subject to the Engineer’s approval.
502-2.02 High-Early-Strength (HES) Concrete. Use HES concrete where required in the contract
documents or where the Contractor’s request to use HES concrete is approved by the Engineer.
Whether required or requested, design the HES mix to satisfy the opening to traffic time requirements
of the project and Table 502-1, High-Early-Strength Concrete Mix Requirements. Submit the HES
concrete mix design to the Engineer. Include admixture brands and dosages as well as mixing,
transporting, placing, paving, curing, and anticipated strength gain details.
Produce and place a 4.0 yd3 (minimum) trial batch at an off-contract location selected by the
Contractor and agreed upon by the Engineer. Produce the trial batch using the same materials and
processes as those to be used to produce concrete for the contract. Provide the Engineer a 7-day minimum
advance notification of trial batch production. Produce and place the trial batch in the presence of the
Engineer, the Regional Materials Engineer, and Materials Bureau personnel.
Provide an American Concrete Institute (ACI) Certified Concrete Field Testing Technician, Grade I,
or higher, to:
• Measure slump, air content, and unit weight of the trial batch.
• Cast cylinders from the trial batch for compressive strength and durability testing.
Determine the compressive strength of the trial batch concrete at the desired time as discussed in
§502-3.16C, Project Strength Determination.
The Materials Bureau will render a decision on mix acceptability, curing, and opening to traffic
requirements within 45 calendar days of trial batch production. Changes other than minor fluctuations in
admixture dosage rates require a new mix design and trial batch. The Engineer will reject the concrete if
the specified plastic air content is not achieved. The Engineer may halt paving and order additional trial
batches whenever the specified compressive strength requirements are not achieved.

2. There are no minimum or maximum requirements for slump, however mix must be
fluid enough to finish without segregating.
502-2.03 Performance Engineered Mixes (PEM). If specified, design a concrete mixture proportioned
to meet the requirements of the contract documents. Procedures for mix approval and acceptance will also
be included in the contract documents.
502-2.04 Load Transfer Dowel Bars. Refer to 705-15 for Dowel bar requirements. If specified, load
transfer dowel bars other than epoxy coated steel may be required. The material requirements as well as
the approval and acceptance procedures will be included in the contract documents.
502-3 CONSTRUCTION DETAILS. Hold a pre-pave meeting 7 to 14 day before the planned start of
paving with the Engineer, any PCC paving and saw cutting subcontractors, and concrete suppliers to
coordinate all aspects of paving and inspection, including equipment review, construction methods, and
time and personnel requirements.
Construct a smooth, well consolidated, properly finished, textured, and cured pavement to the line
and grade depicted in the contract documents, ± 1/4 inch vertically at any location.
502-3.01 Equipment. Provide the Engineer with an equipment list and specifications a minimum of 14
days prior to the planned start of PCC paving. Bring all equipment needed to place, consolidate, finish,
texture, cure, saw cut, seal, and test the PCC pavement to the job site a minimum of 1 full work day
before its use to allow examination by the Engineer. Repair or replace any equipment found to be
defective before or during its use. Discontinue any operation if unsatisfactory results are being obtained.
Use of equipment other than described below is subject to the approval of the Director, Materials Bureau.
A. Slipform Paving. Use a self-propelled slipform paver equipped with:
• Rigid side forms that laterally support the concrete and minimize edge slumping.
• A full-width finishing pan.
• Attached internal vibrators capable of consolidating the entire concrete placement.
Slipform paving consists of a single paver, or a placer/spreader followed by a separate paver,
capable of placing, spreading, consolidating, screeding, and finishing the concrete such that hand
finishing is kept to a minimum. Use equipment guided by a reference system that ensures the
pavement is placed to the specified line, grade, and cross section.
B. Fixed Form Paving
1. Forms. Use straight forms without horizontal joints meeting Table 502-2, Form Requirements,
and equipped with:
• At least 3 stake pockets spaced 3 feet apart (maximum), each having a positive, nondetachable
wedge.
• Positive, interlocking devices capable of holding abutting sections together to form neat, tight
joints.
TABLE 502-2 FORM REQUIREMENTS
Characteristic Requirement
Material Steel, 1/4 inch thick, minimum.
Length 10 feet, minimum.
197 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Flexible, curved, or wooden forms may be used in irregular areas or curved sections having
horizontal radii of 100 feet or less.
2. Paving Equipment. Use fixed form paving equipment specifically made for placing concrete.
The equipment must be capable of placing, spreading, consolidating, screeding, and finishing
the concrete to the specified line, grade, and cross section such that hand finishing is kept to a
minimum. Use equipment with either attached internal vibrators or in conjunction with hand-
held internal vibrators.
C. Vibrators. Use paver-mounted internal vibrators capable of consolidating the entire concrete
placement that are:
• Capable of being shut off without shutting off the paver.
• Equipped with frequency controls readily accessible to the paver operator.
• Capable of simultaneously operating at the same frequency as the other paver-mounted vibrators.
• Capable of operating through a frequency range of 6,000 - 10,000 vibrations per minute.
Check vibrator operating frequencies daily when paving begins. Check frequencies under load
with the Engineer present. If the paver is not equipped with direct-read frequency gauges for each
vibrator, supply the Engineer with a calibrated, hand-held tachometer, including instructions, to
monitor vibrator frequencies. The tachometer will remain the Contractor’s property after paving is
complete.
Use hand-held vibrators capable of operating through a frequency range of 6,000 - 10,000
vibrations per minute in any location that is not consolidated by internal vibrators attached to the
paving equipment.
D. Saw Cutting Equipment. Use diamond blade saws capable of making straight cuts to the
dimensions depicted in the Standard Sheets that are equipped with cutting guides, blade guards, water
cooling systems, dust controls, and cut depth control.
Maintain equipment and supplies to ensure uninterrupted saw cutting. Early entry saws require
approval from the Director, Materials Bureau. Submit requests to use early entry saws at least 7
calendar days before paving.
E. Curing Compound Applicators. Use atomizing mechanical sprayers capable of exerting
consistent pressure without hand pumping that are equipped with tank agitators to continuously mix
the curing compound. Use nozzles with spray shields to prevent drift. Flush nozzles daily before use.
Maintain equipment and supplies, including extra nozzles, to ensure uninterrupted curing
compound application. In a multi-lane slip form paving operation, use self-propelled applicators
guided by the same reference system as the slip form paver. Otherwise, applicators need not be self-
propelled.
F. Drills. Use gang drills with a minimum of 2 independently powered and driven drills. Use
tungsten carbide drill bits. Rest and reference the drill rig frame on and to the pavement surface such
Depth Equal to the sum of the edge thicknesses of all pavement layers
placed within the form.
Base Width Equal to the depth, minimum.
Horizontal Top Face 2 inch wide, minimum, and lying in a plane with a maximum
variation of 1/8 inch in 10 feet.
Vertical Face Maximum variation of 1/4 inch in 10 feet and rounded on the
upper corner with a 3/4inch radius, maximum.
Flange Bracing Extends outward on the base 2/3 of the form depth, minimum.
198 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
that the drilled holes are cylindrical, perpendicular to the surface being drilled, and repeatable in
terms of position and alignment. Hand-held drills are permitted for drilling holes in longitudinal joints
if there is not enough room to use gang drills resting on the pavement surface.
G. Joint Sealing - Highway Joint Sealant. Heat the sealant in a melter constructed either:
• As a double boiler with the space between inner and outer shells filled with oil or other heat-
transfer medium.
• With internal tubes or coils carrying the sealant through a heated oil bath and into a heated
double-wall hopper.
Do not use direct heating. Use a melter capable of maintaining the sealant’s pouring temperature
and providing homogeneous sealant equipped with:
• Positive temperature control.
• Continuous full sweep mechanical agitation.
• Separate thermometers indicating the temperatures of the heat transfer medium and the sealant in
the hopper. Do not place any sealant if the thermometers are defective or missing.
Provide 2 thermometers having stems 18 inches long and temperature ranges sufficient to meet
the requirements of this specification. Use a discharge hose equipped with a controlled heating
apparatus or sufficiently insulated to maintain the proper sealant pouring temperature. Use nozzles
that apply the joint sealant within the joint confines for the full width and depth of the joint.
H. Air Blasting Equipment. Use equipment with traps or other installed devices that prevent
moisture and oil from contaminating the concrete surface. Use a compressor that delivers air at a
minimum of 120 cfm and develops a minimum nozzle pressure of 90 psi. Check the compressed air
stream purity daily with a clean white cloth.
502-3.02 Weather Limitations
A. Rain. Do not pave in the rain. Supply sufficient quilted covers, plastic coated fiber blankets, or
polyethylene curing covers near the paving operation when rain may be expected. Securely cover any
concrete exposed to rain that has not reached initial set or will be visibly affected by the rain.
B. Cold Weather. Place concrete when the air temperature is 40°F and rising, or warmer, and when
the surface temperature of the area to be paved is 40°F, or warmer. Stop paving when the air
temperature falls below 40°F. Measure temperatures in the shade to an accuracy of 1°F. Refer to
§502-3.11C, Cold Weather Curing.
502-3.03 Subbase Course. Install a subbase course in accordance with Section 304, Subbase Course,
before placing PCC. If the area is available, extend the prepared subbase course at the same line, grade,
and cross slope as the area being paved such that it is at least:
• 3 feet beyond the longitudinal edges of a slipform pavement.
• 1 foot beyond the outside longitudinal edges of the fixed forms.
Additional subbase course that is not included in the finished work will be paid for under Section 304
items included in the contract.
502-3.04 Slipform Paving. Establish a reference system to achieve the specified smoothness level. If
string lines are used, set them by survey and use dual lines whenever possible.
199 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Maintain uniform concrete quality and head in front of the paver. Coordinate concrete delivery to
maintain continuous forward movement of the paver and avoid excessive delivery truck queues. Keep
paver tracks clear of concrete and debris before and during paving.
Wet the entire subbase surface without forming puddles or mud immediately before placing concrete.
Consolidate the entire concrete placement using internal vibrators attached to the paver. Combine
paver forward speed, vibrator frequency, and vibrator depth to consolidate the concrete without
segregation, vibrator trails, or contacting the joint assemblies. Discontinue vibration and tamping if the
paver stops.
Determine edge slump by extending a 2 foot (minimum) long straightedge over the longitudinal
pavement edges. Immediately correct edge slumps greater than 1/4 inch that are between concrete
placements and greater than 3/8 inch at free edges and HMA shoulders.
502-3.05 Fixed Form Paving.
A. Setting Forms. Compact the supporting layer at the form line such that the forms are supported for
their full length. Set forms to string lines placed at the pavement elevation, line, and grade and to
achieve the specified smoothness. If a form sits above the string line, remove the form and trim the
form line to the proper grade. If a form sits below string line, remove the form and fill and compact
the low area with granular material at least 6 inches on both sides of the form. Frequently check form
grade and alignment while paving. Reset forms as necessary.
Set forms to accommodate a full day’s paving before placing concrete. Extend forms beyond
construction bulkheads to provide a working platform at the end of a placement. Secure each form
with a minimum of 3 pins, each of sufficient length to hold the forms in place without movement
during any operation. Lock the forms together such that the form ends are aligned and the joints are
tight and smooth. Run the paving equipment atop the forms before placing any concrete and recheck
form alignment. Reset forms as necessary.
Align keyway strips in a smooth, horizontal plane, parallel to the top of the form. Match keyway
strips on abutting forms such that a nearly seamless keyway results.
B. Paving. Apply oil to forms before placing concrete. Immediately before placing concrete, wet the
entire subbase surface without forming puddles or mud. Uniformly distribute the concrete in front of
the paver by maneuvering the delivery truck chute. If concrete is spread by hand, use come-alongs or
shovels. Do not use rakes or hand-held vibrators to spread concrete.
Maintain uniform concrete quality and head in front of the paving machine and without running
over the screeds. Coordinate concrete delivery to maintain continuous forward movement of the paver
and avoid excessive delivery truck queues. Keep form tops clean before and during paving.
Consolidate the entire concrete placement using internal vibrators attached to the paver.
Combine paver forward speed, vibrator frequency, and vibrator depth to consolidate the concrete
without segregation, vibrator trails, or contacting the joint assemblies. Discontinue vibration and
tamping if the paver stops.
Use hand-held vibrators ahead of the paving equipment to consolidate all concrete not
consolidated by machine-mounted internal vibrators. Keep hand-held vibrators perpendicular to the
pavement surface. Vibrate between 2 and 4 seconds in each location, overlapping adjacent locations.
Do not drag vibrators through the concrete. Do not walk through consolidated concrete.
Mark the midpoint (± ½ inch) of each transverse contraction joint such that the saw cut operator
can accurately locate the first-stage saw cut locations.
C. Form Removal. Remove forms after the concrete has developed sufficient strength to allow
removal without damaging the pavement. Repair pavement damaged during form removal. Remove
forms before making second-stage saw cuts.
200 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
502-3.06 Joint Construction. The Engineer will inspect the longitudinal joint ties and transverse joint
supports for compliance to the relevant Materials Details before any joint hardware placement is allowed.
Construct joints in accordance with the Standard Sheets and approved Materials Details. Do not stand on
joint hardware.
Base final joint layout on construction staging and the actual location of utilities, drainage structures,
intersections, tapers, and other irregular areas. Submit a proposed joint layout to the Engineer at least 10
calendar days prior to PCC paving. Obtain the Engineer’s approval of the joint layout before paving.
Inserting dowels and/or longitudinal joint ties into plastic concrete will be considered. Submit a plan
to verify dowel and tie locations, depth, and alignment to the Engineer for consideration. Do not insert
dowels or ties until the plan is approved by the Engineer.
Make first-stage saw cuts 1/8 inch wide. Make second-stage saw cuts, clean, and seal joints in
accordance with §502-3.12, Sealing Joints.
A. Transverse Joints. Transverse joints include contraction, expansion, hinge, and construction
joints. Secure joint supports to the subbase as depicted in the Materials Details. Maintain joint
supports in their proper position and alignment during paving.
Construct transverse joints perpendicular to both the pavement surface and longitudinal joints in
the area being paved. Use a 15 foot maximum transverse joint spacing for pavements having standard
slab widths of 12 to 13 feet. For pavements having other slab widths, determine typical maximum and
minimum transverse joint spacing in accordance with the following:
Lmax = Wmin × 1.33
Lmin = Wmax ÷ 1.33
where:
Lmax = maximum transverse joint spacing (slab length)
Lmin = minimum transverse joint spacing (slab length)
Wmax = maximum slab width across the pavement (load carrying slabs only)
Wmax ≤ 13 feet
Wmin = minimum slab width across the pavement (load carrying slabs only)
1. Transverse Contraction Joints. All transverse joints are contraction joints unless otherwise
shown in the contract documents. Contraction joints are constructed in a straight line across the
full width of the PCC pavement and shoulders. Contraction joints may be angled (rather than
straight across a pavement) at tied longitudinal joints between lanes placed separately if the
placements do not have the same centerline, e.g., where a ramp centerline diverges from parallel
to the pavement centerline. Contraction joints may terminate at, or be misaligned at, untied
longitudinal joints as discussed in §502-3.06B3, Untied Longitudinal Joints.
Store transverse contraction joint support assemblies in inverted stacks at the project site.
Cover stored epoxy coated steel such that it is protected from direct sunlight. Handle joint
supports such that no twisting or bending occurs during storage and positioning. Supports with
bent, twisted, or deformed wires will be rejected.
Before placing concrete, position transverse joint supports such that the:
• Entire longitudinal axis of each dowel is located at the mid-depth of the pavement slab or up
to 1 inch below the mid-depth of the slab.
• Longitudinal axes of the dowels are aligned parallel with the pavement centerline and
pavement surface such that the maximum misalignment of one dowel end relative to the other
is ¼ inch.
• Midpoint of the longitudinal axis of each dowel is at the center of the joint (±1 inch).
201 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
• Longitudinal axes of the two end dowels are 4 to 8 inches from the longitudinal joints.
• Longitudinal axes of the dowels are spaced 12 inches apart.
Mark the location of each contraction joint on the subbase before placing concrete such that
the assembly is properly positioned. Also mark the longitudinal midpoints of the dowels such that
the saw cut operator can accurately locate first-stage saw cuts. In a slipform paving operation,
mark the joint support midpoint on the subbase immediately adjacent to the pavement. In a fixed
form paving operation, mark the joint support midpoint on the form or such that the saw cut
operator can easily locate the joint midpoint. Do not cut the shipping wires.
Make first-stage saw cuts as soon as the concrete has hardened sufficiently to permit sawing
without causing raveling wider than 1/8 inch. Replace blades if raveling persists. Center first-
stage saw cuts within 1 inch of the longitudinal midpoints of the dowels.
Complete first-stage saw cuts before any uncontrolled cracking occurs. Be prepared to make
first-stage saw cuts 24 hours a day to prevent uncontrolled cracking. Provide lighting required to
make first-stage saw cuts at night at no additional cost to the State.
Sweep or wash first-stage saw cut debris from the pavement before it rains, or before opening
the pavement to any traffic, such that debris does not enter the joint.
2. Transverse Expansion Joints. Construct transverse expansion joints as part of the utility and
drainage structure isolation systems depicted in the Standard Sheets or where indicated in the
contract documents. Handle and position expansion joint supports in accordance with
§502-3.06A1, Transverse Contraction Joints.
Construct expansion joints using 1/2 inch thick remolded resilient joint filler placed in 1 piece
between longitudinal joints. Tightly place and support abutting sections of joint filler such that no
concrete infiltrates the joint. Place expansion caps on the dowels as depicted in the Materials
Details. Do not tap or hammer the caps onto the dowels.
No saw cuts are required in expansion joint construction. Remove the finishing cap, if
supplied, after the concrete has developed sufficient strength to prevent damage.
3. Transverse Construction Joints. Construct transverse construction joints wherever there is an
interruption of more than 30 minutes in concrete paving operations. Construct these joints as wide
as the concrete placement, typically 1 or 2 lanes, but not necessarily the full pavement width.
Align construction joints with transverse contraction or construction joints in adjacent lanes.
Construction joints may be formed by bulk heads, saw cuts, concrete removal, or any
combination thereof.
When required, drill and anchor dowels in accordance with §502-3.06D, Drill and Anchor
Dowels or Ties, such that they meet the positioning requirements of §502-3.06A1, Transverse
Contraction Joints.
a. Bulkheads. Ensure the bulkhead can support the weight of the plastic concrete. Bulkheads
may be slotted or solid. Place a slotted bulkhead over the dowels of an exposed joint assembly
such that half of the dowel lengths are embedded within newly placed concrete. Immediately
remove plastic concrete in front of the bulkhead and from the exposed joint support.
The transverse joint assembly may be omitted and a solid bulkhead may be used. In this
case, drill and anchor dowels, if required, into the transverse joint face.
b. Saw Cut. Saw cut full depth construction joints at locations that satisfy the minimum and
maximum slab length requirements of §502-3.06A, Transverse Joints. Saw cut when the
concrete has obtained sufficient strength to be saw cut without damage to concrete to remain
in place. Do not cut within 12 inches of a longitudinal joint tie. Remove the hardened concrete
ahead of the saw cut. Drill and anchor dowels, if required, into the saw cut face such that they
202 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
meet the positioning requirements. Do not drill into longitudinal joint ties.
In lieu of drilling holes, the contractor may use transverse joint supports fabricated with
closed-end, hollow plastic cylinders instead of dowels. Use hollow cylinders with outer
diameters equal to the drilled hole diameters described in §502-3.06D, Drill and Anchor
Dowels or Ties. Position cylinders as required in §502-3.06A1, Transverse Contraction
Joints.
Saw cut the newly placed concrete full depth and full width through the midpoint of the
longitudinal axis of each cylinder (± 1 inch). Remove hardened concrete and the joint
assembly ahead of the saw cut. Remove the hollow cylinder embedded in the concrete that
remains and anchor the dowels in accordance with §502-3.06D, Drill and Anchor Dowels or
Ties, to the required alignment in §502-3.06A1, Transverse Contraction Joints.
c. Removal. Remove all concrete to the midpoint of the preceding transverse joint without
damaging the dowels, dowel coatings, or the pavement to remain in place.
4. Transverse Hinge Joints. Do not place hinge joints without the Engineer’s approval.
Construct transverse hinge joints when a slab length exceeds the geometric requirements of §502-
3.06, Transverse Joints. (This situation typically occurs near structures that are skewed from
perpendicular to the pavement centerline.)
Locate hinge joints such that they are equally spaced between other types of transverse joints.
Construct hinge joints in accordance with §502-3.06A1, Transverse Contraction Joints, except the
positioning requirements do not apply. Instead, position transverse hinge joint supports such that
the:
• Entire longitudinal axis of each deformed bar is located at the mid-depth of the pavement slab
or up to 1 inch below the mid-depth of the slab.
• Longitudinal axes of the bars are aligned parallel with the pavement centerline and pavement
surface such that the maximum misalignment of one bar end relative to the other is 1 inch.
• Midpoint of the longitudinal axis of each bar is at the center of the joint (±1 inch).
• Longitudinal axes of the two end bars are 4 to 10 inches from the longitudinal joints.
• Longitudinal axes of adjacent bars are spaced 4 to 18 inches apart.
B. Longitudinal Joints. When a longitudinal joint item is specified, select tie type, size, spacing, and
positioning in accordance with the 502 Standard Sheets and contract documents. Provide a minimum
clearance of 3 inches between the end ties in a slab and any part of the transverse joint support. Keep
ties free of materials that inhibit bonding to concrete or anchoring material. Maintain ties in their
proper position during paving.
It is highly desirable to align longitudinal joints with the permanent pavement markings. Tied
longitudinal joints located in the wheel paths of the completed pavement will require ties placed 24”
on center.
1. Longitudinal Joints Between Lanes Paved Simultaneously. Use one-piece ties fabricated into
assemblies capable of securely holding 2 or more ties. Secure the assemblies to subbase prior to
paving in accordance with the Materials Details.
Make first-stage saw cuts parallel to the pavement centerline and perpendicular to the
pavement surface before uncontrolled cracking occurs. Use equipment specified in §502-3.01D,
Saw Cutting Equipment. Replace saw blades if raveling wider than 1/8 inch occurs. Center first-
stage saw cuts within 1 inch of the longitudinal midpoint of the ties.
Sweep or wash first-stage saw cut debris from the pavement before it rains, or before opening
the pavement to any traffic, such that debris does not enter the joint.
203 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
2. Tied Longitudinal Joints Between Lanes Paved Separately. In a slip form operation, construct
a butt joint and drill and anchor one-piece ties into the hardened concrete in accordance with
§502-3.06D, Drill and Anchor Dowels and Ties.
Use # 6 ties, 22 inches (minimum) long between travel lanes and 18 inches (minimum) long
between a travel lane and a PCC shoulder. Anchor ties between travel lanes 10 inches into the
previously placed concrete, leaving 12 inches (minimum) projecting from the joint face. Anchor
ties between a travel lane and a PCC shoulder 8 inches (minimum) into the previously placed
concrete, leaving 10 inches projecting from the joint face.
Place end ties in a slab 14 to 18 inches from the transverse joint. Typically, space ties
between the end ties 36 inches apart, maximum. Pavements having 4 or more tied lanes, or 3 lane
pavements 12 inches (or more) thick, may require a decreased spacing in accordance with the
contract documents.
In a fixed form operation, construct either a butt or a keyed joint. Drill and anchor one-piece
ties as discussed above, or use multiple-piece ties. Apply a corrosion inhibiting coating to the
threads of all multiple-piece tie components before assembly. Bolt the female portion of the tie to
the form prior to paving as depicted in the Standard Sheets. Insert and tighten the male ends
before paving the adjacent lane. Ensure all threaded connections are tight.
First-stage saw cuts are not required between lanes paved separately.
3. Untied Longitudinal Joints. Construct untied longitudinal joints at utilities and/or drainage
structures, at intersections, between adjacent lanes having non-parallel center lines (such as
ramps), or where indicated in the contract documents. Form as depicted in the Standard Sheets.
Transverse joint type, location, and alignment may be changed when a transverse joint intersects
an untied longitudinal joint.
Patch honeycombing along the untied longitudinal joint face to achieve a smooth surface
prior to applying the bond breaker and placing the adjacent concrete.
First-stage saw cuts are not required.
C. Utility and Drainage Structures and Telescoping Manholes. Detail jointing around each utility
and drainage structure in the proposed joint layout submitted to the Engineer for approval. Refer to
the Standard Sheets for jointing and reinforcement around utilities and drainage structures. When
possible, do not isolate, or “box out,” utilities and drainage structures from the pavement. Instead, set
and center utilities and drainage structures between transverse joints and pave the slab with the
structure at the same time as the surrounding pavement. Use a minimum slab length, Lmin, as defined
in §502-3.06A, Transverse Joints. Reinforce the slab that contains the structure. Select reinforcement
size and spacing such that:
As ≥ 0.0018(s)(t)
where:
As = Area of a steel bar (in2)
s = Spacing of steel bars (in). Minimum 3” clearance between bars.
t = Slab thickness (in)
Use mat reinforcement with steel in both directions. Use top and bottom double mat
reinforcement for slabs thicker than 10”. Refer to the Standard Sheet for mat reinforcement placement
locations.
When using telescoping manholes, remove temporary support bolts from the telescoping manhole
casting as soon as the concrete hardens.
204 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
D. Drill and Anchor Dowels or Ties. Do not drill holes until the concrete has developed sufficient
strength to withstand drilling without damage. Damage from drilling shall be addressed in accordance
with §502-3.14, Damaged or Defective Concrete.
Drill such that the hole diameters are in accordance with the anchoring material manufacturer’s
written recommendations. Replace worn bits when necessary to ensure the proper hole diameter is
drilled.
Follow the anchoring material manufacturer’s written recommendations for cleaning the holes.
As a minimum, clean the drilled holes with compressed air. Insert the nozzle to the back of the hole to
force out all dust and debris.
When using new cartridges of anchoring material, ensure the initial material exiting the nozzle
appears uniformly mixed. If it is not uniformly mixed, waste the material until uniformly mixed
material extrudes.
Place the anchoring material in the back of the hole using a nozzle with sufficient reach. Push the
dowel or tie into the hole while twisting such that the air pocket within the hole is heard to burst and
the anchoring material is evenly distributed around the bar. Use sufficient amounts of anchoring
material such that it slightly extrudes out the hole as the bar is inserted.
502-3.07 Paving Adjacent To Existing Concrete. Wherever paving equipment operates on existing PCC
pavement that is to remain, install bolt-on track covers or rubber tired, flangeless wheels. Remove all
debris on the existing PCC pavement in the equipment track. Immediately remove any concrete that
spills onto the existing concrete.
When paving from (or to) a transverse construction joint or intersecting pavement, use hand-held
vibrators to thoroughly consolidate any concrete inaccessible to the paving equipment vibrators. Hand
finish these areas with the minimum effort required to produce an acceptable surface. Do not dump the
grout box head into the pavement concrete when approaching a construction joint.
502-3.08 Plastic Thickness Determination. Provide the Engineer with a round, rigid, nonaluminum
probe, having a 1/8 inch diameter. The Engineer will determine the plastic concrete thickness by inserting
the probe and measuring the insertion depth. The Engineer will check thickness at least every 150 feet of
paving and at least 2 feet from the placement edge. Keep several probes at the project.
The minimum measured plastic thickness must be equal to (-1/4 inch) or greater than the thickness
required in the contract documents. Areas not meeting minimum thickness will be treated in accordance
with §502-3.14, Damaged or Defective Concrete. If 2 consecutive measurements do not meet minimum
thickness, stop paving and reestablish the paving operation to achieve acceptable thickness.
502-3.09 Finishing. Provide an ACI certified concrete flatwork finisher to supervise finishing. Provide
proof of ACI flatwork certification to the Engineer.
Mechanically finish the pavement after consolidation and strike off. Use machine mounted finishers
such as full-width finishing pans, transverse oscillating screeds, longitudinal floats, pan floats or separate
pieces of equipment such as tube floats. Correct bumps with a 16 foot straight edge or bump cutter
specifically made for finishing concrete.
After mechanical finishing, hand finish the pavement to correct and seal minor imperfections. Hand
finish with magnesium floats, lutes, and/or trowels. Use work bridges to hand finish concrete inaccessible
from the pavement edge. Keep hand finishing to a minimum. Do not use excess mortar or discarded
concrete to fill low areas. Do not add water to the concrete surface to close imperfections. Do not trowel
bleed water into the surface. Stop paving or reformulate the
concrete mix if surface imperfections that require additional water to close routinely occur.
Ensure the saw cut operator can locate joint sealant locations between separate, adjacent placements.
This may be accomplished with a small radius (1/4 inch) edger along the edge of the second placement.
205 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
502-3.10 Texturing. Immediately after finishing and prior to applying the curing compound, texture the
concrete surface using one of the following procedures in accordance with the contract documents. Apply
longitudinal tining if no texturing method is designated in the contract documents. Additional
requirements, such as Mean Texture Depth measured by a sand patch test or a profiler may be performed
to check texturing adequacy. For a closed drainage system, provide an 8 - 12 inch blank in the texture
along the pavement edges to enhance drainage to catch basins.
A. Longitudinal Tining. Texture the concrete parallel to the pavement centerline with a set of evenly
spaced spring steel tines. Use rectangular tines 1/8 inch wide, 1/32 inch thick, and approximately 5
inches long at a center-to-center spacing of 3/4 inches.
Operate the tine head manually or mechanically. In either case, hold the tines as near an angle of
45° to the concrete surface as possible to minimize mortar dragging. Produce tine texture 1/16 - 1/8
inch deep with minimal dislodging of aggregate. Do not make multiple tine passes in the same area.
Keep tines 2 - 4 inches from the placement edges. Keep the tines free of hardened concrete.
B. Artificial Turf Drag. Use a seamless strip of artificial turf drag appearing on the Department's
Approved List entitled “Turf Drag” under “Equipment, Concrete Related.” Produce a consistent
texture, free of ridges or gouges, parallel to the pavement centerline either by hand or by attaching a
weighted strip to the paver, texture/cure machine, or work bridge. Periodically replace or clean the
drag to remove hardened concrete paste that compromises texture.
502-3.11 Curing. Apply curing compound no later than 5 minutes after texturing. The Engineer may stop
paving if curing lags beyond the time limits noted. Cure Class C concrete placed between June 1 and
September 15 for 4 days, minimum. Cure Class C concrete placed between September 16 and May 31 for
6 days, minimum. Cure HES or alternate mixes in accordance with Materials Bureau requirements based
on the Contractor-submitted mix design and the trial batch evaluation.
A. White Pigmented Membrane Curing Compound. Cure concrete with white pigmented membrane
curing compound. Mix the curing compound before each use and continuously agitate during use.
Uniformly coat all exposed surfaces (including slipformed edges and formed edges immediately after
form removal) at a minimum rate of 150 sf/gal such that the coated surfaces are completely white.
Check the application rate after every paving day, including exposed vertical slab faces in the
calculations. Apply the curing compound in 2 direction passes with no longer than 15 minutes
between passes.
Immediately reapply curing compound to any damaged coating areas before the curing compound
sets. During curing equipment breakdown, cure the pavement in accordance with §502-3.11B, Curing
Covers. Do not apply curing compound in the rain. If rain damages the curing compound before it
sets, reapply curing compound after the pavement surface dries.
B. Curing Covers. Use of curing covers is subject to the approval of the Engineer. Use quilted covers,
plastic coated fiber blankets, or polyethylene curing covers. Do not use covers with tears or holes.
Cover all exposed surfaces and extend the covers a minimum of 12 inches beyond the pavement
edges or beyond the forms, when used. Overlap successive covers 12 inches, minimum. Secure the
covers to keep them in contact with the entire surface and maintain the overlap. Wet the entire surface
of quilted covers and maintain them in a wetted condition until pavement is eligible to be opened to
construction traffic.
C. Cold Weather Curing. Supply form insulating materials for winter concreting when the air
temperature is going to fall below 40°F at any time until pavement is eligible to be opened to
construction traffic. Use material capable of maintaining a surface temperature of 55°F and being
easily removed and replaced to accommodate first-stage saw cuts. Apply the insulating material to
206 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
prevent newly placed concrete from being exposed to air temperatures below 35°F for the curing
period. Secure the insulation tight to the concrete surface to prevent air intrusion beneath the
insulation. Extend the insulation 12 inches beyond the newly placed concrete. Insulate the pavement
vertical edge and/or forms as well.
Place recording surface thermometers between the pavement surface and insulating material 12
inches from one of the placement edges wherever insulation is used. Use 4 equally spaced
thermometers for each day’s paving. Do not subject the concrete to a temperature drop in excess of
50°F during the first 24 hours after removing the insulation.
502-3.12 Sealing Joints. Seal joints in accordance with the Standard Sheets.
First-stage saw cuts may be temporarily left unfilled if a placement is only subjected to occasional
construction traffic, such as pickup trucks or cars. In this case, ensure debris does not enter the joints.
Temporarily fill unsealed first-stage cuts with jute or backer rod if a placement is:
• Subjected to consistent construction traffic.
• Used as a haul road for subsequent concrete placements.
• Temporarily opened to general traffic while final sealing has been delayed for convenience, such as to
maximize sealing production.
Before cleaning, remove any temporary fillers and repair damaged joints in accordance with
§502-3.14, Defective or Damaged Concrete, including chipped joints resulting from debris accumulation
in an unfilled or unsealed joint.
A. Highway Joint Sealant. Widen joints to 1/4 - 3/8 inch for a depth of 1 inch to allow full-depth
sealing. Immediately wash the widening cut slurry from the pavement such that it does not reenter the
joint.
Clean the joints by abrasive blasting before sealing. Keep the nozzle within 2 inches of the joint
surfaces. If the project does not allow abrasive blasting, The Engineer may allow pressure washing as
an alternate preparation method. When pressure washing, use (1) a 900 psi minimum pressure and (2)
a maximum pressure such that no damage occurs to the concrete. Manually dislodge debris remaining
in the joint after cleaning, and reclean the joint. Immediately after pressure washing, air blast the joint
to remove any debris from the cut and dry the exposed faces. Ensure the joint is completely dry
before sealing.
Do not allow any traffic on the pavement between cleaning and sealing. Reclean the joint if it
rains between cleaning and sealing or if any traffic is on the placement between cleaning and sealing.
Provide the Engineer a copy of the sealant Manufacturer's written recommendations for heating
and application at least 1 work day before sealing. Follow those recommendations. Unless stated
otherwise, the recommended pouring temperature is 40°F below the manufacturer's designated safe
heating temperature, with an allowable variation of 40°F.
Prior to sealing, discharge sealant from the applicator wand into a vessel and measure the sealant
temperature. The temperature must be equal to or above the Manufacturer’s recommended minimum
pouring temperature and equal to or below the Manufacturer’s recommended safe heating
temperature.
Do not use sealant heated above the safe heating temperature. Sealant may be reheated or heated
in excess of 6 hours if allowed by the Manufacturer’s heating and application recommendations. In
these cases, recharge the melter with fresh sealant amounting to at least 20% of the sealant volume
remaining in the melter.
Seal joints immediately after cleaning. Seal the joint from the bottom of the cut to within 1/2 inch
of the pavement surface. Seal when the:
• Air and surface temperatures are 40°F or warmer.
• Air temperature is above the dew point.
207 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
• Pavement surface and all joint surfaces are dry.
Open to traffic after the sealant has cured to prevent tracking. Do not blot with fine aggregate.
B. Sealing Joints - Preformed Joint Sealers. Make second-stage saw cuts and/or bevels in
accordance with the Standard Sheets and (1) no sooner than 72 hours after concrete placement and (2)
after the curing period has ended if curing covers are used. Extend the second-stage saw cut vertically
down the free concrete edges. Wash the resulting slurry from the pavement and joint immediately
after making second-stage saw cuts and/or bevels.
Second-stage saw cuts may be delayed for convenience, but do not leave second-stage saw cuts
unsealed or unfilled while open to any traffic. Temporarily fill second-stage saw cuts with jute or
backer rod if (1) they are exposed to any traffic before cleaning and sealing or (2) weather conditions
are not favorable for timely (within 2 calendar days) cleaning and sealing, whether or not they are
exposed to any traffic.
Clean the joints by pressure washing before sealing. Use (1) a 900 psi minimum pressure and (2)
a maximum pressure such that no damage occurs to the concrete. Manually dislodge debris remaining
in the joint after cleaning, and reclean the joint. Within 24 hours of pressure washing, air blast the
joint to remove any debris from the cut and dry the exposed faces. Reclean the joint if it rains
between cleaning and sealing. Do not allow any traffic on the pavement between cleaning and
sealing.
Install the sealant in accordance with the Manufacturer’s written instructions. Lubricate the
concrete, the sealer, or both before installation such that the lubricant fully covers the sealer/concrete
interface, but not the top of the sealer.
Install one piece of transverse joint sealer in a compressed condition across the full pavement
width, including concrete shoulders, and down the vertical saw cut at the free edge. Cut the
longitudinal sealer where it crosses a transverse joint. Do not splice the longitudinal sealer between
transverse joints. Seal the intersection between longitudinal and transverse sealers with lubricant.
Install the sealer such that it is not stretched more than 5%, nor compressed more than 2%, of the
minimum theoretical length. Check the installation for stretch and compression by installing sealers in
5 transverse joints and removing the sealer immediately after installation and checking the length. An
alternate method for checking stretch and compression, where applicable, may be performed by
premarking or precutting the sealer to length prior to installation. If the measurement of any of these 5
sealers exhibits stretching in excess of 5% or compression in excess of 2%, modify the installation
method to meet the requirements or discontinue installation.
Once sealing operations begin, remove 1 joint per 100 in the presence of the Engineer to check
stretch and compression. If the sealer is found to be stretched in excess of 5% or compressed in
excess of 2%, remove the sealer material from successive joints in both directions until sealers are
found that meet the stretch and compression requirements. Replace all joints sealers found with
excess stretch or compression. Replace joint sealers removed and found to meet the stretch and
compression requirements.
502-3.13 Pavement Protection. Protect the pavement and appurtenances from traffic and construction
operations. Protect the work and provide for traffic as indicated in the contract documents.
502-3.14 Damaged or Defective Concrete. The Engineer will identify all areas of damaged and
defective concrete. Submit a repair plan for the damaged or defective concrete to the Engineer for
approval. Repair or replace all damaged or defective concrete in accordance with the approved repair
plan. Damage and defects include, but are not limited to, cracking, spalling, poor consolidation, out of
specification materials, or imperfections caused by inadequate pavement protection, traffic, and/or
construction practices. Slipformed concrete with inadequate plastic thickness as described in §502-3.08,
Plastic Thickness Determination, will be rejected in 150 foot segment lengths.
208 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
502-3.15 Hardened Surface Tolerance. After the concrete has hardened sufficiently, test each travel
lane, including ramps, with straight edges laid both longitudinally and transversely. Do not measure
transverse deviations across longitudinal joints. The Engineer will mark longitudinal deviations in the
pavement surface exceeding 1/4 inch in 15 feet and transverse deviations exceeding 1/4 inch in 10 feet.
Diamond grind these deviations in accordance with §505-3.02, Bump Grinding, such that they do not
exceed these parameters when retested.
Shoulders and other areas not routinely exposed to traffic must meet 1/4 inch in 10 feet both
longitudinally and transversely.
502-3.16 Opening to Traffic
A. Construction Traffic. Open Class C concrete pavement to construction traffic and paving
equipment at least 7 days after placement. With the Engineer’s approval, the time may be shortened to
3 days if cylinders meet the requirements of Table 502-3 Pavement Opening Requirements. Any
pavement damaged from opening to construction traffic in a reduced time frame will be treated in
accordance with §502-3.14, Damaged or Defective Concrete.
B. General Traffic. Open Class C concrete pavement to general traffic placed between June 1 and
September 15 at least 10 days after placement. Open Class C concrete pavement to general traffic
placed outside of the above dates at least 15 days after placement.
With the Engineer’s approval, these times may be shortened to 4 days if cylinders meet the
requirements of Table 502-3 Pavement Opening Requirements, and the joints are addressed in
accordance with §502-3.12, Sealing Joints.
Any pavement damaged from opening to general traffic in a reduced time frame will be treated in
accordance with §502-3.14, Damaged or Defective Concrete.

209 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
If these conditions are not met, test 3 additional cylinder pairs at a later time, provided the
appropriate numbers of additional cylinders were cast. If the above conditions are not met after
additional testing, or, if the required number of additional cylinders were not cast, open the pavement
in accordance with the nonreduced time frames of §502-3.16A, Construction Traffic, and
§502-3.16B, General Traffic.

E. Maturity. ASTM C1074, Standard Practice for Estimating Concrete Strength by the Maturity
Method, may be used to open the pavement to traffic. Inform the Engineer of the intent to use this
method at least 28 days before producing any pavement concrete. Submit a maturity curve
development plan to the Engineer that includes an equipment list, the date and time of batching, the
testing facility name and address, which must meet §502-3.16C, Project Strength Determination,
requirements, and any variations to ASTM C1074. Perform all batching and testing related to
developing the maturity curve with the Engineer and Regional Materials Engineer present. Open to
traffic at the strengths identified in Table 502-3 Pavement Opening Requirements.
502-4 METHOD OF MEASUREMENT. The Engineer will measure the following quantities for items
incorporated into the finished pavement:
502-4.01 PCC Pavement, Unreinforced. The work will be measured for payment as the number of cubic

551-3 CONSTRUCTION DETAILS
551-3.01 General. The method of storing and handling of piles shall be such as to avoid damage to the
piles. Piles shall not be driven until after the excavation is completed to the elevation required for the
bottom of the footing or bottom of tremie. Unless otherwise shown on the Plans, any material forced up
or depressions made by the driving shall be removed or filled and the correct elevation of foundation
established before any concrete is placed.
The driving of piles shall be done with an air/steam, diesel, or hydraulic hammer. Piles shall be driven
starting from the center of the foundation and proceeding outward from this point, or starting at the
outside row and driving progressively across the foundation.
The length of piles will be determined in the field by driving to the driving criteria determined by the
DCES. Piles may be completely driven in one operation or, if directed by the DCES, be partially driven
and allowed to set from 2 to 24 hours (or as indicated on the Plans) before driving is resumed.
Piles shall be vertical or accurately battered as indicated on the Contract Plans. The top of any pile
driven its full length into the ground shall not vary from the plan location by more than 4 inches, unless
otherwise shown on the Plans. The top of any pile partially exposed or included in an integral abutment
shall not vary from the plan location by more than 1 inch, unless otherwise shown on the Plans. Piles may
have a variation at their tip of not more than ¼ inch per foot from the vertical or from the batter shown on
the Plans or permitted by the DCES.
All piles forced up by any cause shall be driven again, at no additional cost to the State.
The following shall be causes for rejection of a pile:
• Pile location or batter is incorrect.
• Pile damaged from any cause whatsoever.
• Pile fails to attain the driving resistance determined by the DCES, or the driving resistance set
forth in the contract documents.
• Pile tip elevation is not within the limits called for in the contract documents.
• Pile is unserviceable for other reasons related to the furnishing and installing of the pile.
• Cast-In-Place Concrete Pile Casing not free from water.
No footing concrete shall be placed until all piles within the footing are inspected by the Engineer.
The Contractor shall remove rejected piles, or at the option of the Department, a second pile may be
driven adjacent thereto, if this can be done without impairing the structure.
The tops of all piles and pile casings shall be cut off at the elevation indicated on the Plans, or as
established by the Engineer. The cut shall be clean, level, and to a true plane, in accordance with the
detail shown on the Plans.
218 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
All cavities left by the pile driving operation shall be backfilled.
551-3.02 Steel H-Piles. Steel H-Piles shall be furnished with a shoe, fabricated as detailed on the Plans,
or as approved by the DCES. Substitution of commercial shoes for those detailed on the Plans may be

a NYSDOT Certified Welder with a 5/16 inch minimum fillet weld along the entire outside edge of the
flanges.
551-3.03 Cast-In-Place Concrete Piles. Pile casings which do not hold their original form during
driving, which fracture, or fail during driving due to manufacturer defect, fabrication, or Contractor's
operations, unless otherwise directed, shall be replaced at no additional cost to the State. If, at any time
during the driving or placing of the pile casings, the DCES determines from the results of the driving that
the pile casings of the type or thickness being used cannot be satisfactorily placed, the Contractor shall
remove the casings, and replace them with casings of the type and thickness directed at the expense of the
State.
All pile casings shall be equipped with a toe treatment as shown on the Plans.
Cast-in-place concrete piles shall be reinforced as shown on the Plans and the reinforcement secured
in such a manner as to ensure its proper location in the finished piles.
Cast-in-place concrete pile casings shall be inspected immediately prior to placing concrete in the
casing. All casings in the footing shall be satisfactorily placed and dry before concrete is placed. Each
casing shall be filled with a continuous pour of Class A concrete, mixed and placed in accordance with
Section 555 Concrete for Structures, except that the slump of the concrete shall not exceed 5 inches.
Care shall be exercised in filling the piles to prevent honeycomb and air pockets from forming in the
concrete. Internal vibrators and other means shall be used to the maximum depth practicable to
consolidate the concrete.
All exposed pile or pile casing surfaces not embedded in concrete shall be painted in accordance with
the Contract Documents.
551-3.04 Furnishing Equipment for Driving Piles. The Contractor shall submit to the DCES for
approval Form BD 138 Pile Driving Equipment Data a minimum of 21 calendar days prior to beginning
pile driving work. Each separate combination of pile and pile driving equipment proposed by the
Contractor shall require the submission of a corresponding Form BD 138.
Piles shall be driven only with equipment which has the prior approval of the DCES. All
malfunctioning equipment shall be removed from the site and be replaced with equipment which is
satisfactory to the DCES. The minimum rated striking energy of the hammer to be used in driving Steel
H-Piles and Cast-In-Place Concrete Piles shall be 13 kip-feet per blow.
Hammers having greater striking energy may be used upon approval by the DCES. These hammers
shall produce a minimum of 20 blows/foot and a maximum of 120 blows/foot at the Nominal Pile
Resistance shown on the Contract Plans. However, if, in the opinion of the DCES, satisfactory results are
not obtained with the hammer furnished by the Contractor, a hammer meeting the approval of the DCES
shall be furnished and used.
Water jets and vibratory hammers shall not be used in driving any pile, unless written approval is
given by the DCES. Piles installed with a water jet or vibratory hammer shall be impact driven to secure
the final penetration.
A. Air/Steam Hammers. Sufficient boiler or compressor capacity shall be provided at all times to
maintain the rated speed of air/steam hammers during the full time of pile driving. The valve
mechanism and other parts of a single or double-acting hammer shall be maintained such that the
number of blows per minute for which the hammer is designated, is satisfied.
219 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
B. Diesel Hammers. Single acting hammers’ valves, pumps, ports, rings, and other hammer parts
shall be maintained such that the length of stroke, or blows per minute is satisfied.
All diesel hammers shall be provided with an acceptable means of measuring hammer energy.
C. Hydraulic Hammers. Hydraulic hammers that have enclosed rams, shall be equipped with an
electronic printout. Those which have exposed rams, shall be visually inspected.
D. Hammer Cushion. An approved hammer cushion block shall be used to transfer pile hammer
energy to the pile. Each hammer shall be equipped with a helmet/drive head to fit the type of pile to
be driven.
The hammer cushion will be inspected for compliance with the description in the BD 138 prior to
driving the first pile, and thereafter every 100 hours of driving. The hammer cushion will be re-
inspected if a hammer with a different serial number is brought to the project.
E. Pile Driving Leads. Pile driving leads shall be constructed in such a manner as to afford freedom
of movement of the hammer. The use of either swinging or hanging leads will be permitted provided
the pile or leads are properly supported during driving and the required final position and batter of
pile is achieved. If the use of swinging or hanging leads produces unsatisfactory results, the
Contractor shall hold the leads in position with guys or braces to give the required support or use
equipment having fixed leads.
Pile driving leads shall be of sufficient length so that the use of a follower will not be necessary.
The driving of piles with followers will generally not be permitted and shall be done only with written
permission and direction of the DCES.
When directed by the Engineer, approved steel spuds shall be used to penetrate consolidated
material or obstructions in the upper 10 feet in order to assist in driving the piles to the required depth
and resistance. Augers may be used for this purpose with written approval from the DCES.
551-3.05 Dynamic Pile Load Testing. Dynamic pile load tests will be conducted by the Department
under the direction of the DCES. The Contractor shall furnish a source of electrical power, a suitable test
enclosure to perform field testing of piles and evaluate pile hammer efficiency and all incidental labor and
material necessary to make the work area accessible.
Tests shall be performed at the locations indicated on the Contract Plans and where directed by the
Engineer. A Dynamic Pile Load Testing Procedure, known as the "Impact Driving Method", will be
used. This procedure entails the following steps:
1. Prior to being struck with the pile driving hammer, each pile to be tested will be instrumented
with strain and acceleration transducers by State personnel, aided by the Contractor's forces.
2. Dynamic measurements resulting from the pile hammer blows will be automatically recorded on
a pile driving analyzer supplied by the State and operated by State personnel.
3. Upon determination by the Engineer that valid data has been recorded, State personnel, assisted
by the Contractor's forces, will remove the instrumentation.
The Contractor will schedule equipment movements to ensure that testing is done as part of the
normal driving schedule, insofar as it is possible.
551-3.06 Splices. Full length piles shall always be used where practicable. Pile splices shall be
constructed as shown in the contract documents, or as approved by the DCES. Where splices are
unavoidable, their number, locations, and details will be subject to the approval of the DCES. Pile splices
at less than 10 feet beyond the estimated length shall be installed at no additional cost to the State. A
second splice may be used at 30 feet beyond the estimated length, subject to DCES approval.
220 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Splices to steel H-Piles, and steel pile casings shall be welded in conformance with the provisions of
the Steel Construction Manual (SCM) These requirements include, but are not limited to, a NYS certified
welder and a DCES approved welding procedure.

230 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
specifically for the control of water, or other material as indicated in the cofferdam design submitted for
review.
553-3 CONSTRUCTION DETAILS
553-3.01 Cofferdams. Cofferdams shall be constructed so as to keep the excavations free from earth,
water, ice, or snow, and to permit excavations to be carried to the depths indicated on the plans.
Cofferdams, when used in conjunction with a tremie pour, shall be designed and constructed to
automatically flood by non-mechanical means such as over topping or flooding ports. The automatic
flooding elevation shall be as indicated by note in the plans.
In the event that permanent or temporary sheeting is required by the plans at the location of the
cofferdam, the Contractor may elect to incorporate this material into the cofferdam system. Additional
bracing may be required to satisfactorily perform excavation, dewatering, and other required construction
operations. The permanent sheeting system shall be returned to its intended condition after all cofferdam
equipment and material, including any additional bracing, has been removed. All damage done to the
temporary system, if still required, or permanent sheeting, shall be repaired at the Contractor's expense, to
the satisfaction of the Engineer.
Unless otherwise indicated on the plans, cofferdams shall be maintained in a dewatered condition
during foundation construction. The placement of foundation concrete shall not be impeded by water
standing or flowing within the cofferdam.
If a waterway diversion structure is approved as a substitution, all of the requirements of §553-3.02
Temporary Waterway Diversion Structure shall apply.
Dewatering equipment and any additional bracing shall be of adequate quality and capacity and shall
be so arranged as to permit their proper functioning in connection with the cofferdam. Dewatering
equipment and bracing shall be so located to permit construction of the structure in accordance with the
plans.
All damage caused by the failure of a cofferdam to perform its proper functions shall be the
responsibility of the Contractor. It shall also be the Contractor's responsibility to protect all stream banks
from erosion by reason of restriction of the channel caused by the erection of the cofferdam to limits
greater than that shown on the plans for the Contractor’s own convenience. In that situation, all material
which erodes from the banks during that time the cofferdam is in place shall be replaced by the Contractor
at the Contractor's own expense. The Engineer, in consultation with the regulatory permit agency(ies)
representative(s), will be the sole determiner of the nature and extent of all damages and mitigation

SECTION 554 - FILL TYPE RETAINING WALLS (Last Revised May, 2020)
554-1 DESCRIPTION. This work shall consist of furnishing and installing a fill type retaining wall at
the location(s) and to the elevation(s) shown in the contract documents.
554-1.01. General. The fill type classification refers to the construction method used for the installation
of the wall. Fill type retaining walls are retaining structures constructed from the base of the wall to the
top (i.e. “bottom-up” construction).
The fill type retaining walls are further classified according to the basic mechanism of lateral load
support. These classifications include internally stabilized fill structures and externally stabilized fill
structures.
The specification is supplemented with an Approved List which provides a listing of available
designers and their corresponding fill type retaining walls. Fill type retaining walls are further defined in
the pertinent subsequent section. For proprietary fill type retaining wall systems, approved designers, wall
systems, and the components of each wall system appear on the Approved List, available on the
Department’s web site. Designers wishing to have their wall systems reviewed for placement on the
Approved List shall follow the procedural directives of the Geotechnical Engineering Bureau as contained
in Highway Design Manual Appendix 9A.
554-1.02 Definitions. Internally stabilized fill structures are structures which rely on friction developed
between closely-spaced reinforcing elements and the backfill to resist lateral soil pressure and are
subcategorized in the retaining wall subsections of this specification. Externally stabilized fill structures
are structures which utilize the weight of the wall system elements and the weight of the infill to resist
lateral soil pressure.
A. Wall System. A wall system is either a series of open top face units assembled to form bins
which are connected in unbroken sequence or a combination of specific solid face units with a
characteristic alignment and connection method, which utilize the weight of the wall system elements
and the weight of the infill to resist lateral soil pressure. As indicated, the bin volume is infilled with
backfill material to supplement the face unit geometry, adding to the stability of the system.
B. Internally Stabilized Wall System. A wall system which, when constructed beyond wall
heights exceeding the maximum allowable unreinforced height per the Approved List, relies on
reinforcing elements within the backfill to provide stability.
C. Internally Stabilized Earth System. A series of tensile reinforcing elements which, when
placed in multiple layers within the backfill volume, improves the strength such that the vertical face
of the stabilized earth volume is essentially self supporting.
D. Internally Stabilized Fill Structures.
1. Fill Structure. A fill type retaining wall as described in §554-1.01 Fill Type Retaining Walls
which consists of either an internally stabilized wall system or an internally stabilized earth
system.

555-3 CONSTRUCTION DETAILS
258 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
555-3.01 Concrete Manufacturing and Transportation. Unless otherwise specified in the contract
documents, the construction details for manufacturing and transporting concrete shall comply with §501-
3, Portland Cement Concrete - Construction Details.
555-3.02 Falsework. Falsework plans shall be submitted by the Contractor and approved by the
Engineer before falsework construction is started. Falsework or centering shall be designed for the dead
load of the concrete forms, the dead load of the plastic concrete (based on 150 pcf) and a live load
resulting from a weight of 50 psf applied to all horizontal surfaces.
Falsework which cannot be founded upon a solid footing, shall be supported by falsework piling.
Screw jacks or hardwood wedges may be required for falsework centering or to take up any slight
settlement in the form work, either before or during the placing of concrete.
Falsework shall be set to give the finished structure the specified camber, plus allowance for
shrinkage and settlement.
555-3.03 Forms.
A. General. All forms shall be well constructed, carefully aligned, substantial, and firm, securely
braced, and fastened together in their final position. They shall be strong enough to prevent the fresh
concrete from bulging the forms between supports and to withstand the action of mechanical
vibrators. If required by the Engineer, form work plans shall be submitted by the Contractor and
approved by the Engineer before forms can be used on the work.
Forms shall be designed to resist a dead load resulting from a weight of 150 pcf for the plastic
concrete and a live load resulting from a weight of 50 psf on horizontal surfaces. The form and
falsework design shall provide for the loads resulting from any conveyance system in addition to the
live load.
When concrete is transported by buggies, conveyor belt, or other approved methods of
conveyance, the forms shall be capable of supporting the distribution equipment and any
concentrations of concrete which may occur during transportation and distribution. Buggy runways
and other supporting platforms shall be supported directly by the forms.
Forms shall be adequately braced to resist concrete design loads. If the forms are inadequately
braced concrete placement shall stop until adequate bracing has been provided.
All forms shall be set and maintained true to the line designated until the concrete is sufficiently
hardened. Forms shall be maintained to eliminate the formation of joints due to shrinkage of the
lumber. Forms shall be sufficiently tight to prevent leakage of mortar.
Forms may be constructed of wood, metal, or other approved materials, except when a particular
material is specified in the contract documents. The use of fiber forms will be permitted for round
columns only if the interior surface of the forms have been treated in such a manner as to prevent
helical corrugation marks on the finished concrete surfaces. Forms shall be filleted 1 inch with
forming material at all exposed corners to create a chamfer in the finished concrete unless otherwise
shown in the contract documents.
When curved, patterned, or other special forms are required, the Contractor shall submit details
of the form construction to the Engineer for approval prior to constructing the forms. Forms shall be
so constructed that those surfaces on which finishing may be required may be stripped without
disturbing the remaining forms. Premanufactured formliner panels, if used, shall be capable of
imprinting the surface of the concrete with a uniform and aligned pattern and texture. The panels
shall be composed of elastomeric urethane, polyvinyl chloride (PVC), ABS plastic, or other suitable
material for their intended shape and number of reuses to achieve the desired effects. Formliners
shall leave crisp, sharp definition of the architectural surface. Sufficient liners shall be used to
minimize pattern repeat. Formliners shall not compress more than 1/4 inch when concrete is poured
at a rate of 10 vertical feet per hour.
259 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Any metal ties or anchorages within the forms shall be so constructed that the embedded portion
of the ties can be removed to a depth of at least 2 inches from the surface of the concrete without
damage to such surface. Wire ties shall not be used without written approval of the Engineer. In
case wire ties are approved, all wires, upon removal of the forms, shall be cut back at least 1/4 inch
from the face of the concrete with sharp chisels or nippers (nippers are necessary for green concrete).
All cavities produced by the removal of metal ties shall be filled in conformance with requirements
of §555-3.11, Corrective Finishing.
For walls where access to the bottom of the forms is not practicable, the lower form boards or
panels shall be left loose so that the inside of the forms can be readily cleaned of all chips, dirt,
sawdust, or other extraneous material, immediately prior to the placing of concrete.
Forms to be reused shall be maintained in good condition as to accuracy of shape, strength,
rigidity, watertightness, and smoothness of surface. Any warped or bulged forms must be carefully
resized before being re-used. Forms that are unsatisfactory in any respect shall not be used. All form
surfaces that will be in contact with the concrete shall be thoroughly treated with an approved form
coating in the manner, and at the rate specified by the manufacturer. Only those coatings listed on
the Approved List published by the Materials Bureau are acceptable. Forms so treated shall be
protected against damage or dirt prior to placing concrete.
If metal forms are used, the material shall be of such thickness that the forms will remain true to
shape. All bolt and rivet heads shall be countersunk. Clamps, pins,or other connecting devices shall
be designed to hold the forms rigidly together and to allow removal without damage to the concrete.
Metal forms, which do not present a smooth surface or line up properly, shall not be used. Special
care shall be exercised to keep metal forms free from rust, grease, or other foreign matter that would
tend to discolor the concrete.
B. Foundation Concrete. The footings of structures shown in the contract documents shall be
considered as approximate only, and when ordered in writing by the Deputy Chief Engineer
(Structures), shall be changed to such dimensions as will give a satisfactory foundation. Concrete
shall not be placed in any foundation form without the Engineer’s approval.
555-3.04 Handling and Placing Concrete.
A. Placement Limitations. No concrete shall be placed when the ambient air temperature is below
45°F, unless the Engineer grants approval to a written proposal from the Contractor. No concrete
shall be placed during rain.
When concrete is to be placed in contact with steel members, reinforcing steel, or previously
placed concrete, the temperature of the steel and concrete shall be raised to approximately 45°F. The
use of enclosures and heating equipment, including but not limited to the use of forced hot air, hot
water boilers, and hoses, or other methods suitable to the Engineer, may be required before
concreting begins.
When concrete is to be placed in contact with earth or rock, within piles, or for tremie placements,
the temperature of the earth or rock shall be 35°F or higher. The earth or rock shall not have any
snow, ice, frost, or standing water on its surface. The use of insulating materials and heating
equipment may be required before concreting begins.
B. Conveyance. Concrete shall be placed so as to avoid segregation of materials and
displacement of reinforcement. All equipment used for conveying the concrete mix, from the point
of delivery and material acceptance to the discharge point, shall be capable of meeting the
permissible variations given in Table 555-1, Concrete Conveyance Uniformity. Prior to the actual
placement of concrete, the Contractor shall demonstrate the capability of the equipment to convey the
concrete mixture. Tests according to Department written instructions will be performed by, and at
260 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
the discretion of the Engineer. No further verification of the equipment capability will be required
unless evidence of nonuniform concrete is observed during placement.
When concrete pumps are used, the lines shall have a minimum diameter of 5 inches. Concrete
pumps with smaller hose diameters may be used for small placements, where mixtures using a CA1
gradation (smaller aggregates) are allowed, and where access is limited. The pumping operation shall
be performed in such a manner as to discharge concrete horizontally a minimum distance of 3 feet.
Where horizontal discharge is not possible, the use of double 90-degree bends at the end of the pump
hose, reducer hoses, or other equipment capable of maintaining a head of concrete in the pump line
may be allowed, subject to the approval of the Director, Materials Bureau.
All chutes, troughs, and pipes shall be kept clean and free from coatings of hardened concrete by
thoroughly flushing with water after each use. Water used for flushing shall be discharged clear of
the concrete already in place.
Concrete shall not come in contact with any aluminum during conveying and placing operations.
TABLE 555-1 CONCRETE CONVEYANCE UNIFORMITY
Test
Permissible Variation
(Concrete samples taken at two
locations in the handling process)
Air Content, % by volume of Concrete 1.5%
Slump Average slump 4 inches or less 1 inch
Average slump greater than 4 inches 1 1/2 inches
C. Acceptance/Testing. The concrete mixture, prior to placement into the conveying equipment,
shall meet the specified requirements for air content and slump given for the various classes and types
of placement under Table 501-3, Concrete Mixtures.
D. Placement. All foreign matter of every kind shall be removed from the interior of the forms
before placing concrete. Temporary studs or braces within the forms shall be removed when the
concrete has reached an elevation rendering their further use unnecessary. Dropping concrete a
distance of more than 5 feet or depositing a large quantity at any point and running or working it
along the forms shall not be permitted. Dropchutes shall be used between vertical forms unless
conveyance equipment can be inserted between forms.
Special care shall be taken to fill each part of the form by depositing concrete directly into the
form as near to its final position as possible, to work the coarser aggregates back from the face of the
concrete and to force the concrete under and around the reinforcement without displacing the
reinforcement. After the concrete has taken its initial set, care shall be exercised to avoid jarring the
forms or placing any strain on the ends of the projecting reinforcement.
Concrete shall be placed in horizontal layers not more than 1 foot thick except as hereinafter
provided. When less than a complete layer is placed in one operation, it shall be terminated in a
vertical bulkhead. Each layer shall be placed and consolidated before the preceding layer has taken
its initial set to prevent damage to the green concrete and avoid cold joints between batches. Each
layer shall be consolidated using appropriate vibrating practices so as to avoid the formation of a
joint with a preceding layer which has not taken initial set.
When concrete placement is temporarily discontinued, the concrete, after becoming firm enough
to retain its form, shall be cleaned of laitance and other objectionable material to a depth sufficient to
expose sound concrete. To avoid visible joints as far as possible upon exposed faces, the top surface
of the concrete adjacent to the forms shall be smooth and level whenever concreting is discontinued.
Where a “feather edge” would be produced at a construction joint, as in the sloped top surface of a
wing wall, an inset form work shall be used to produce a blocked out portion in the preceding layer
261 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
which shall produce an edge thickness of not less than 6 inches in the succeeding layer. Work shall
be continuous from the bottom to the top of any face.
When embedding structural shapes in concrete, the placement of concrete shall be progressed on
one side of the shape only until it flushes up over the bottom flange of the shape on the opposite side,
after which concrete shall be placed on both sides to completion.
E. Vibration. During and immediately after deposition, concrete shall be thoroughly consolidated
by vibrating the concrete internally with mechanical vibrating equipment. The use of external
vibrators will be permitted when satisfactory surfaces cannot be obtained by internal vibration alone
or when it is impossible to use internal vibrators. The use of external vibrators shall be subject to the
approval of the Engineer. External vibrators shall be attached to or held on the forms in such a
manner as to effectively vibrate the concrete in a horizontal plane.
Internal mechanical vibrators shall be adequately powered, capable of transmitting vibration to
the concrete in frequencies of not less than 5,000 vibrations per minute while inserted in concrete and
shall produce a vibration of sufficient intensity to consolidate the concrete into place without
separation of the ingredients. If any of the reinforcing steel has epoxy coating, an internal
mechanical vibrator shall have a rubberized or elastomeric cover to prevent damage to the epoxy
coating on the reinforcing bars. The vibrators and covers shall be inspected for defects prior to use.
A sufficient number of vibrators shall be employed, so that at the required rate of placement,
thorough consolidation occurs throughout the entire volume of each layer of concrete. Extra
vibrators shall be on hand for emergency use and when other vibrators are being serviced.
The vibrating element shall be vertically inserted in the concrete mass at a depth sufficient to
vibrate the bottom of each layer effectively inserting the vibrator into the underlying lift. It shall be
withdrawn completely from the concrete before being advanced to the next point of application.
Internal vibrators shall not be placed directly on the forms or the reinforcing steel. The vibratory
element shall be inserted vertically into the concrete at the point of deposit and in areas of plastic
concrete at evenly spaced intervals not farther apart than the radius over which the vibration is
visibly effective and at a distance close enough to the forms to effectively vibrate the surface
concrete. The time of vibration shall be of sufficient duration to accomplish thorough consolidation,
complete embedment of the reinforcement, produce dense, smooth surfaces free from aggregate
pockets, honeycombing, and air bubbles and to work the concrete into all angles and corners of the
forms however, over-vibration shall be avoided. Vibration shall be continued in one place until the
concrete has become uniformly plastic, but not to the extent that pools of grout are formed.
Vibration shall be supplemented by working or spading by hand in the corners and angles of
forms and along form surfaces while the concrete is plastic. Vibrators shall not be used to push or
distribute the concrete laterally.
555-3.05 Depositing Structural Concrete Under Water.
A. General. Use a tremie tube, pipeline, or similar method to place concrete under 32 - 90°F water
in one continuous operation. Since the tremie tube and the pipeline are both tubes, the word "tube" in
this specification refers to either type, except where specific reference is made to either the tremie
tube or the pipeline.
Unless noted differently on the plans, use Class G concrete as described in Table 501-3, Concrete
Mixtures. Substitute Class GG Concrete when clear openings between closely spaced objects such
as reinforcement bars are less than 3 inches. Pozzolan replacement may be omitted for small
placements in a fresh water environment when approved by the DCES.
In addition to §555-3.03 Forms, place concrete on prepared areas cleaned of all debris, mud, or
other unsuitable material.
Submit a list of equipment, including back-up, and a schedule for transporting and placing
concrete, to the Engineer for review at least 20 working days prior to concrete placement. The
262 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Contractor shall be responsible to design a tremie placement, with appropriate forming, that
maintains a minimum vertical rise of 1 foot per hour for the overall area and a minimum placement
rate of 40 cubic yards per hour, unless fluid concrete pressure requires a reduced placement rate.
Place fresh concrete before stiffening and initial set of the adjacent concrete to ensure a good
bond and avoid cold joints. If a delay occurs, determine stiffening and initial set by probes or other
methods approved by the Engineer. Stop the operation if the placement cannot be continued before
initial set of the adjacent concrete. The Engineer will then immediately contact the DCES.
B. Methods of Placement. The tremie tube and pump and pipeline are the most common methods.
Obtain approval of the DCES for any other method.
1. Tremie Tube Method (Open System). This method uses a vertical tube open at the top,
where concrete is delivered to the top and falls down the tube.
a. Tremie tube size shall be based on the delivery system used by the Contractor.
Delivery System Inside Diameter
Large volume, such as crane and bucket 10 inches minimum
Small volume, such as pump line or conveyor 5 inches minimum
b. Use a sturdy hopper or funnel with a bottom opening smaller than the tremie tube diameter to
transfer concrete into the tremie tube. The capacity and shape of the hopper or funnel depends on
the volume and type of concrete delivery system. A device with the same size bottom opening
may be used if a 1 1/2 to 2 inch diameter breather tube is installed to reach 1 foot or more down
into the tremie tube.
c. Install a safe work platform at the top of the tremie tube.
2. Pump and Pipeline Method (Closed System) This method uses a vertical tube, attached to a
closed tube system, where concrete is pumped to the top and falls down the tube.
a. Use pipe with a minimum inside diameter of 5 inches.
b. Install a minimum 2 inch diameter air vent or valve connection, or leave the pipe joint loose
without a gasket, near the high point of the downgrade, 1 to 4 feet below the point where concrete
starts falling down the pipe, to allow air displaced by concrete to escape, and admit air to prevent
a siphoning effect.
c. Class G concrete, the mix noted on the plans, or a “cement-water” grout may be used for
pipeline lubrication and placed in the forms. Waste any other concrete mix used to lubricate
pipeline.
C. Placement Tubes for Tremie Tube or Pump and Pipeline Method. Clearly mark each tube in at
least 1 foot increments (numbered every 5 feet) to show depth to the outlet. Use watertight joints.
Place tubes no more than 15 feet from the forms and no more than 30 feet on center.
1. Open end tubes Install a separate tube at each placement point, as loss of seal occurs when
the embedded end of this tube type is removed from fresh concrete under water. Once started, do
not relocate or remove open end tubes until completion of the concrete placement at that location.
If loss of seal occurs, remove and seal the tube with a watertight plate or plug for restarting.
Restart tremie placement only if a seal can be reestablished using a dewatered tube where the
outlet can be surrounded by fresh concrete.
263 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
2. End-valve sealed tubes Install the number of tubes based on the minimum placement rate
defined in A. General, as the seal is maintained when the embedded end of this type is removed
from fresh concrete under water. Raise the end of the tube to about 3 feet below the fresh
concrete surface. Then, close the valve with the tube 1/2 full of concrete (1/2 the water depth),
and slowly remove the tube. Reverse this procedure upon relocation in fresh concrete.
D. Dewatering. When necessary, proceed with dewatering at least 4 days after completion of
concrete placement, unless noted differently on the Contract Plans or as ordered by the Engineer.
After dewatering, continue curing and excavate one or more sumps to provide for pumping of
accumulated water. Excavate sumps outside of areas which will receive new concrete, or as
approved by the Engineer.
E. Concrete Evaluation.
1. Nondestructive Testing. Use as directed by the Contract, or as approved by the DCES.
2. Cores. Obtain cores in the presence of the Engineer at locations and to depths shown on the
contract plans. Take NX size (2 1/8 inch) cores, no earlier than 7 days after concrete placement,
according to §648-3.04, Rock Core Samples, B. Sampling, the 1st sentence. Use drill bits
meeting the requirements of Subsection 732-06, Coring Bits.
Obtain 100% recovery from each core hole, as less is presumed to indicate defective
concrete. Use a 5 foot nominal length of core drill run. Record core boring log data in
accordance with §648-3.01B, Driller’s Logs.
Label and pack all cores according to §648-3.04 C, Marking, Packaging and Transporting
Samples. Deliver and store the core boxes at a site approved by the Engineer, where they become
the property of the Department. Provide assistance in moving and arranging core boxes at the site
to facilitate evaluation by the Department.
F. Defects. Obtain additional cores for further investigation from areas which contain voids,
honeycombing, seams, or other defects. The DCES will determine the number and location of
additional core holes. Repair defects with grout when approved by the DCES. Placements with
defects determined to be unrepairable by grouting will be rejected. Alternate repair techniques
require DCES approval.
G. Grout Repairs and Grout Placements. This section only applies for underwater grout
placements limited to quickly filled areas, such as core drill holes, small piles up to 1 foot in diameter,
and other small voids. Use materials meeting §701-05, Concrete Grout Material, for the grout
proportioned as specified or as approved by the DCES.
When the DCES grants approval for repairs, the proposed grouting method shall be performed by
cleaning out and filling all defects and core drill holes with grout. Position a grout tube (2 inches or
less in diameter) about 1 inch off the bottom of the prepared hole until the grouting operation is
complete. Start pumping (closed system) or filling a tremie tube (open system) faster than the grout
can fall through water. Continue placing grout until the grout coming back out the hole is the same
consistency as that going in. Then withdraw the tube.
Additional cores may be required to verify acceptable repairs.
H. Tremie Construction Joints. Prepare the top area of the placement receiving new concrete to
within 3 inches of the elevation shown on the plans. When joining fresh concrete to concrete that has
already set, the concrete in place shall have its surface scoured or abraded with a suitable tool to
remove all loose and foreign materials. After the surface preparation, the concrete surface, and all
porous surfaces to be in contact with new concrete shall be thoroughly wet using potable water for 12
264 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
hours with soaker hoses or the use of burlap/burlene/etc. to maintain moisture. The Contractor shall
remove any puddles of free-standing water with oil-free compressed air, and protect the surfaces from
drying, so the existing concrete remains in a clean, saturated, surface-dry condition until placement of
the new concrete.
Fill any low areas with a leveling course of Class A concrete (or Class D for 1 1/2 to 5 inches
thick placements).
Fill sumps with concrete or stone, as ordered by the Engineer.
555-3.06 Concrete Joints.
A. Construction Joints. Construction joints for the purpose of these specifications are joints used
to provide for interruptions in the placement of concrete. Construction joints shall be placed only
where shown in the contract documents or where approved by the Deputy Chief Engineer
(Structures). Bulkheads required during placement shall be constructed at the direction of the EIC.
Unless otherwise shown in the contract documents, a shear key shall be provided at each
construction joint by embedding water-saturated wooden blocks in the plastic concrete. The shear
key thus provided shall be approximately 1/3 of the width of the parts joined. The key depth shall
equal the thickness of standard form lumber, approximately 1/2 the key width. Shear keys need not
exceed 5 1/2 inches in depth regardless of the key width.
On steel truss or open-spandrel, concrete arch spans, unless otherwise noted in the contract
documents, the concrete in the floor system shall be placed about the center line of the span,
beginning at the center and working simultaneously toward each end; or beginning at the ends, and
working simultaneously toward the center. Care shall be taken to prevent the displacement of
reinforcement during the placing of concrete. If, for any reason, it becomes necessary to introduce a
construction joint, this shall be formed by means of a vertical bulkhead so constructed as to produce
a key joint, placed as shown in the contract documents or as permitted by the Deputy Chief Engineer
(Structures).
When joining fresh concrete to concrete that has already set, the concrete in place shall have its
surface scoured or abraded with a suitable tool to remove all loose and foreign materials. After the
surface preparation, the concrete surface and all porous surfaces to be in contact with new concrete
shall be thoroughly wetted, to achieve a saturated surface dry condition, using potable water for 12
hours with soaker hoses or the use of burlap/burlene/etc., to maintain moisture. If conditions or the
situation prohibits this, then the surfaces should be wetted for as long as possible. The Contractor
shall remove any puddles of free-standing water with oil-free compressed air, and protect the
surfaces from drying, so the existing concrete remains in a clean, saturated surface-dry condition
until placement of the new concrete. Immediately before placing the new concrete, the forms shall
be drawn tightly against the concrete already in place.
Forms for female shear keys shall be beveled on four sides to facilitate their removal and shall be
securely fastened to the forms to prevent displacement before the concrete has set. Key forms shall
be removed in such a manner as to avoid damage to the concrete.
B. Contraction Joints. Contraction joints shall be placed at locations shown in the contract
documents and unless otherwise specified, shall be formed the same as construction joints, except
that reinforcement shall not extend through the joint.
C. Expansion Joints. Expansion joints shall be placed as shown in the contract documents.
Expansion joints shall provide for expansion, contraction, and the transfer of shear at the joint, unless
otherwise specified. When expansion joints are formed by the insertion and subsequent removal of
joint templates, this work shall be done in such a manner that joint edges are not chipped or broken
down in the process.
265 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
When concrete is to be placed against a joint filler, holes or joints in the filler shall be suitably
filled with mastic to prevent mortar or concrete from entering the joint and restricting its movement.
The face edges of all joints shall be carefully finished or formed true to line and elevation for a
minimum distance of 2 inches back from all exposed surfaces.
When caulking compound is used to seal a joint containing premolded bituminous joint filler, a
layer of an approved type of pressure-sensitive release tape shall be placed between these materials
due to their incompatibility.
D. Waterstops. Waterstops shall be installed in joints to provide for expansion and contraction
movements at joints. Place waterstop at all joints exposed to view, as shown in the contract
documents, or as ordered by the Engineer. Waterstop shall be a polyvinyl chloride or other approved
flexible material, copper strip, zinc strip or lead sheet. The waterstop shall extend at least 3 inches
into the concrete on each side of the joint, shall be joined to be continuous and watertight, and shall
be carefully protected from damage until covered by concrete or backfill.
555-3.07 Finishing.
A. General. All exposed unformed surfaces, whether permanent or at construction joints, shall be
finished by placing an excess of material in the forms and striking off the excess with a suitable float,
forcing the coarse aggregate below the level of the finished surface, and troweled to a suitable finish.
The use of mortar topping for surfaces shall not be permitted.
Following the discontinuance of placing concrete, all accumulation of mortar splashed upon the
reinforcing steel and the surfaces of forms shall be removed. Dried mortar chips and dust shall not
be puddled into the plastic concrete.
B. Bearing Surfaces. The entire surface area of bridge seats or pedestals shall be floated and
troweled to true grade or, at the option of the Contractor, left approximately 1/4 inch high and bush
hammered or otherwise finished to the exact elevations indicated in the contract documents.
555-3.08 Curing.
A. General. All structural concrete shall be cured for a minimum of seven curing days unless
otherwise stated. The curing period shall begin only after all curing procedures and practices for a
given placement are established. A curing day is defined as any day during which the ambient air
temperature at the concrete surface is 45°F or higher for the entire day.
Conditions may occur which prevent an entire day from qualifying as a curing day, but do not
prevent portions of that day from reaching temperatures that qualify as curing temperatures. If these
conditions occur and with the Engineer's approval, the Contractor may aggregate curing hours. A
curing hour is defined as any hour during which the curing temperature remains at, or above 45°F.
An aggregation of 24 curing hours will be credited as one curing day. Aggregations of less than 24
curing hours will not be credited.
Curing hours will be determined with continuous recording thermometers. The number and
placement of the thermometers will be determined by the Engineer. Thermometers used to monitor
curing temperatures shall consist of the following types:
1. Continuously Recording Thermometer. The thermometer shall be capable of continuously
recording temperatures within a range of 0°F to 120°F for a minimum of 24 hours.
2. Maximum - Minimum Recording Thermometer. For all placements, the thermometer shall
be capable of recording maximum and minimum temperatures within a range of 0°F to 120°F.
Provide all equipment, supplies, and labor necessary for calibration.
266 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The curing temperature of concrete is the air temperature at the concrete surface, or the air
temperature between the concrete surface and its protective covering. Temperatures at these
locations are critical for proper concrete curing. For the purposes of this section the temperatures
at the foregoing locations shall be maintained between 45°F and 85°F inclusive.
All structural concrete surfaces must be cured by any one, or a combination of, the following
methods unless otherwise noted:
• Polyethylene curing covers - white opaque.
• Plastic coated fiber blankets.
• Clear (fugitive dye) membrane curing compound.
• Continuous burlap wetting.
• Wet burlap and curing covers.
• Forms left in place
Curing shall commence on all exposed surfaces no later than 30 minutes after completion of
finishing. Finishing and curing operations shall progress with concrete placement.
Curing covers shall be placed as soon after concrete finishing as the Engineer determines will not
cause damage to the concrete surface. However, under no circumstances shall the curing be delayed
beyond 30 minutes of the completion of finishing. Care shall be taken so as not to damage the
finished surface or texturing. Curing covers shall be lapped a minimum of 1 foot. All lapped edges
shall be sealed with pressure sensitive tape. Covers shall be protected from displacement.
Clear (fugitive dye) membrane curing compound shall be sprayed on the concrete surface
immediately following the finishing operation, or form removal, whichever is applicable. The
compound shall be applied by means of a pressure spraying system, or by distributing equipment, at
a minimum rate of 150 sf per gallon of surface. The equipment for applying the compound shall be
such that the compound is applied as a fine spray with no surface damage to the concrete. The
equipment shall also provide for adequate agitation of the compound during application, and shall be
approved by the Engineer before work is started. Should the application method produce a
nonuniform film, or should the spraying equipment fail and back-up equipment is not immediately
available, the application shall cease. Curing shall then be continued by another acceptable method.
The Contractor shall provide sufficient approved covers for protection of the concrete surface in the
event of rain or equipment breakdown.
If forms are removed during the curing period (refer to §555-3.09), the concrete curing shall be
continued using a clear (fugitive dye) membrane curing compound applied immediately after form
removal.
B. Provisions for Curing in Hot Weather. When forms are left in place in extremely hot weather
the forms shall require wetting to reduce surface heat.
If the ambient air temperature exceeds 85°F, continuous, uniform wetting for curing shall be
required until the seven (7) day curing period is complete and forms are removed. Use of plastic
sheeting over the established curing is not allowed in hot weather conditions.
C. Provisions for Curing in Cold Weather. If the ambient air temperature falls, or is expected to
fall below 45°F, the requirements of Table 555-2 shall apply.

Prior to use, all proposed methods must meet the approval of the Engineer. If the curing
temperature falls below 32°F at any time during the curing period, the concrete will be rejected.
To provide assurance of the curing temperatures, the Contractor shall supply thermometers
meeting the requirements of §555.3.08A. Temperature measurements will be taken by the Engineer
and a record will be maintained for the curing period. As a minimum, thermometers shall be placed
adjacent to forms at the bottom, middle, and top of a placement. Additional thermometers may be
placed in areas where extreme cold or heat, from external sources, can be expected.
If the existing method employed by the Contractor to maintain the curing temperature fails, the
Contractor shall modify the existing method immediately to reestablish an acceptable curing
temperature.
The length of the curing period will be extended until the required number of curing days are
accumulated.
1. General. When approval is granted in writing by the Engineer for cold-weather concreting,
the curing temperature shall be maintained between 45°F and 85°F for the curing durations
stated by provision of external heat or utilization of heat of hydration retained by insulated
forms. Only when temperatures are maintained between 45°F and 85°F will the time be
considered acceptable curing hours.
2. Provision of External Heat. If the Contractor is required, or elects, to maintain curing
temperatures by this method, the Contractor shall furnish sufficient canvas and framework, or
other type of housing, to enclose and protect the structure. The enclosure and heat source(s)
shall be established in such a way that the air surrounding the fresh concrete, on all sides, be
kept at a temperature between 45°F and 85°F for the specified curing period. At the end of
the curing period, the heat shall be gradually reduced at a rate not to exceed 1 degree F per
hour until the temperature within the enclosure equals the temperature
outside the enclosure. Materials and equipment necessary to erect the enclosure and provide
external heat shall be present on the job site and approved by the Engineer before any
concrete is placed.
External heat shall be provided by means of stoves, salamanders, heated hoses, steam
equipment, warmed curing water, or other equipment supplied by, operated by the
Contractor. Heating appliances shall not be placed in such a manner as to endanger
formwork, centering, or expose any area of concrete to drying out or damage due to excessive
temperatures. Sufficient equipment shall be supplied to continuously maintain the specified
temperature with a reasonable degree of uniformity in all parts of the enclosure. The
enclosures shall be properly vented to prevent surface disintegration of fresh concrete due to
an accumulation of carbon dioxide gas. All exposed concrete surfaces within the heated area
shall be protected from drying by one of the following methods:
• Use of live steam.
• Continuous wet burlap or wet burlap used with curing covers.
• Curing compounds used with curing covers.

When using concrete containing pozzolans, do not consider the pozzolons as part of the cement content. Use
values given for a Portland cement content that are equal to or less than the actual cement content of the mix,
due to a lower heat of hydration when using pozzolans.
269 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
temperatures will not drop below 32°F. If the Contractor elects to maintain curing
temperatures by this method, sufficient insulation shall be furnished to protect and maintain
the temperature between the insulation and formwork within the range of 45°F to 85°F for the
specified curing period.
Discontinuance of protection shall be accomplished in such a manner that the drop in
temperature of any portion of the concrete shall be gradual. The surface temperature of
concrete sections more than 2 feet in thickness shall not drop faster than 18°F in a 24-hour
period. The surface temperature of concrete sections less than 2 feet in thickness shall not
drop faster than 36°F in a 24 hour period.
Forms may be removed without restriction, providing the temperature difference between
the air and the surface of the concrete is not more than 30°F. If possible, forms shall be
removed about the middle of the day to take advantage of the generally higher afternoon
temperatures.
Form insulating material shall be installed on the forms in such a manner so as to achieve
the full benefit of its insulating properties and at the same time provide against the infiltration
of wind and water. All portions of steel forms shall be covered by insulating material so that
no steel is exposed to the air. Any tears or damaged areas in the insulating material shall be
repaired. Special attention shall be given to ensure that all corners and angles are properly
insulated and protected against wind damage.
Where tie rods extend through the form insulating material, a plywood washer (¾ x 6 x 6
inches approx.) shall be placed over the tie rod and secured against the insulating material.
After placement of the concrete, the exposed concrete surfaces shall be covered with
insulating blankets, except for areas where protruding reinforcing bars make the use of
blankets impracticable. These areas may be covered with hay or other acceptable insulating
material. Tarpaulins shall be used to protect the insulating material.
Insulating material shall be insulating blankets, solid foam, or sprayed foam meeting the
requirements of §711-07, Form Insulating Materials for Cold Weather Concreting. The
appropriate R value of material shall be used to insulate the concrete according to Table 555-3.
Multiple layers of insulation may be used to attain the desired level of insulation (R
value), to maintain the required curing temperatures. Extra care shall be taken in insulating
edges and corners where additional layers or overlaps are required.

Notes:
1 The minimum times for loading in this table are NOT applicable when using concrete that contains fly ash or
ground, granulated blast furnace slag that is placed and/or cured when ambient temperatures are 60°F or less. The
provisions in Note 3 are required for casting, curing, and testing of compressive strength cylinders for concrete that
contains fly ash or ground, granulated blast furnace slag that is placed and/or cured when the ambient temperature is
60°F or less. The compressive strength results will be the basis of determining when loading can occur.
2 All concrete shall be cured for a minimum of seven curing days. A “Day” is a curing day as defined in Subsection
555-3.08A. Concrete surfaces being cured using forms, covers, or blankets from which the covers are removed for any
purpose prior to the full cure period shall be sprayed with an approved clear (fugitive dye) curing compound within ten
minutes of cover removal.
3 When early loading is requested, the minimum time requirements for loading may be reduced (or extended) based
on test cylinder compressive strength results. The DCES will establish requirements for early loading upon request.
The Contractor shall notify the Engineer, in writing, at least 10 days prior to placement, that early loading is being
requested, so that arrangements for test cylinders can be made. Test cylinders shall be prepared in accordance with
Materials Method 9.2 – Field Inspection of Portland Cement Concrete. Two test cylinders shall be prepared for each
anticipated testing period. These cylinders shall be cured in the same manner as the substructure element which they
represent. After the first compression test, the Engineer shall determine subsequent testing periods based on the results
of the first test. No more than three tests for each substructure element shall be allowed.
4 Minimum time for loading pedestals shall not compromise minimum loading times specified for other placements.
555-3.09 Form Removal. Forms shall be removed in such a way as to permit the concrete to take the
stresses uniformly and gradually. Any method of form removal likely to cause overstressing of the
concrete shall not be used.
The forms for any portion of a structure shall not be removed until the concrete is strong enough to
resist damage. The earliest time of form removal shall be as specified in Table 555-4, Minimum Time for
Form Removal - Substructures. If the form removal causes damage, the operation must stop immediately
until such time that sufficient concrete strength is achieved. All damage shall be repaired in conformance
with §555-3.13, Damaged or Defective Concrete.
555-3.10 Loading Limitations. Forms used for substructure concrete placements shall be removed in
accordance with the requirements of Table 555-4, Minimum Time for Form Removal - Substructures.
The minimum times for loading in this table are NOT applicable when using concrete that contains fly
ash or ground, granulated blast furnace slag that is placed and/or cured when ambient temperatures are
60°F or less. The provisions in Note 3 are required for casting, curing, and testing of compressive
strength cylinders for concrete that contains fly ash or ground granulated blast furnace slag that is placed
and/or cured when the ambient temperature is 60°F or less. The compressive strength results will be the
basis of determining when loading can occur.
555-3.11 Corrective Finishing. Immediately after forms have been removed, surfaces exposed to view
shall have all projections and irregularities carefully removed and all cavities greater than 1 inch in
diameter and/or 1/4 inch in depth neatly filled with mortar of the proportion used in the concrete. The
same brand of cement and the same kind of aggregate shall be used for filling cavities as was used in the
superstructure loads. (3)

original concrete mix. Plastering of surfaces shall not be allowed. The surface film (drying cement
paste) of all such repaired surfaces shall be carefully removed before setting occurs.
All rust and other stains shall be removed from concrete exposed to view. Removal shall be
accomplished using methods and materials approved by the Engineer. Materials used for rust stain
removal shall be as listed on the Approved List published by the Department's Materials Bureau.
555-3.12 Weep Holes. The Contractor shall construct weep holes in all retaining walls and abutments
as indicated in the contract documents.
555-3.13 Damaged or Defective Concrete. All defects or damage to concrete which occurs prior to
the final acceptance of the work shall be repaired or replaced at no additional expense to the State. The
defects shall include but are not limited to spalling and irregular cracking at joints, edge spalls,
honeycombing, and damage or other imperfections caused by traffic and/or construction operations. Any
concrete requiring complete replacement shall be replaced in kind as concrete originally called for in the
contract documents. Any repairs shall be performed to the methods described in these specifications
unless otherwise approved by the Engineer. When a repair is made, the defective or damaged concrete
shall be removed by saw cutting the perimeter to a depth of 1 1/2 inches, chipping the unsuitable material
to sound concrete with light, hand held, pneumatic tools at a 45 degree angle into the patch area, and
cleaning all exposed reinforcing and concrete surfaces. All surfaces to be repaired shall be thoroughly
blast cleaned. Prior to placing repair concrete, all surfaces shall be wetted to a saturated surface dry
condition.
Small spalls of 0.1 cy or less, and areas of 10 sf or less where concrete removal is required may be
repaired using approved Concrete repair materials. Vertical or overhead surfaces may be patched with
Vertical and Overhead Patching Material. Surface preparation for small repairs shall be according to the

557-1 DESCRIPTION. The work shall consist of placing high performance (Class HP) concrete to
construct superstructure slabs, sidewalks, safety walks, and structural approach slabs, as required by the
contract documents.
557-2 MATERIALS
557-2.01 General. The materials used for superstructure slabs, sidewalks on bridges, and structural
approach slabs shall meet the material requirements of the following subsections:
Structural concrete materials 555-2.01
Reinforcing steel 556-2
Prestressed concrete form units 718-05
Permanent Corrugated Metal Forms for Bridge Slabs 736-01
557-2.02 Concrete. This shall meet the material requirements for Class HP in accordance with §501.
Unless otherwise directed by the Engineer, all concrete shall contain a water-reducing and retarding
admixture, meeting the requirements of §711-08. The quantity of the admixture shall be sufficient to
achieve the minimum retardation consistent with placing conditions to keep the entire placement plastic
278 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
(either one continuous placement or all sections of a sequence placement). The dosage rate used shall be
determined by the Contractor in accordance with the manufacturer’s recommendation and in concurrence
with the Regional Materials Engineer. The dosage shall remain consistent for the duration of the concrete
placement except for minor adjustments to meet changing environmental conditions.
557-2.03 HPIC Concrete This shall meet the requirements of 557-2.02 HP Concrete with the following modifications: 1. The maximum w/c ratio is 0.40. Do not include absorbed moisture of the light weight fine
aggregate as part of the w/c ratio calculation.
2. Substitute lightweight fine aggregate, meeting the requirements of AASHTO M 195, for 30% (by volume) of standard fine aggregate.
The Regional Materials Engineer, or his representative, will approve the batch weights prior to use. Use
these values to manufacture all internally cured high performance concrete and periodically correct the
batch weights to account for changes in the fine aggregate fineness modulus and aggregate moisture
contents.
557-3 CONSTRUCTION DETAILS
557-3.01 Concrete Manufacturing and Transportation. The requirements of §501-3 shall apply.
A. For HPIC additional requirements follow:
1. Construct lightweight fine aggregate stockpile(s) at the production facility so as to maintain uniform moisture throughout the pile. Using a sprinkler system approved by the Materials Engineer. Continuously and uniformly sprinkle the stockpile(s) with water for a minimum of 48 hours, or until the “Absorbed Moisture content” of the aggregate in the stockpile is at least 15% by weight as determined by Test Method NY 703-19E (https://www.dot.ny.gov/divisions/engineering/technical-services/materials-bureau/forms-manuals). If a steady rain of comparable intensity occurs, turn off the sprinkler system at the direction of the Materials Engineer, until the rain ceases. At the end of the wetting period, or after the rain ceases, allow stockpiles to drain for 12 to 15 hours immediately prior to use, unless otherwise directed by the Materials Engineer.
2. The moisture content of the lightweight fine aggregate must be determined immediately prior to batching, using Test Method NY 703-19E. If the supplied mix design is based on “oven dry” weight of lightweight fine aggregate, a corresponding adjusted weight must be supplied to account for the actual absorbed moisture content, so that the mix design entered in to the automated batching system is based on SSD weight. After the adjusted mix design is entered into batching system, additional adjustments must be made to the fine aggregate and water quantities to account for the “surface” moisture of the fine aggregates.
3. The lightweight fine aggregate, at the time of batching must be at least 15% absorbed moisture content. Batch the lightweight fine aggregate first, then routinely batch the fine aggregate, coarse aggregate, admixtures, cement, pozzolan, Microsilica, and remaining mixing water and mix completely.

measurements will be taken prior to commencement of concrete placement. If, in the Engineer's opinion,
significant changes occur in atmospheric conditions, additional atmospheric measurements and
calculations by the Contractor will be required. The Contractor shall supply all instruments necessary to
make the required calculations. All instruments shall be approved by the Engineer, as being in good
working order. The Contractor’s measurements and calculations will be subject to the Engineer's
approval. To determine the evaporation rate, apply the values taken for relative humidity, plastic
concrete temperature, air temperature, and wind velocity to Figure 557-1 Structural Concrete Evaporation
Rate.
The placing of concrete for any bridge slab shall be continuous between joints. Conveyance of
concrete shall meet the requirements of §555-3.04B.
Vibrating of concrete shall be in accordance with §555-3.04E except the number of vibrators
required shall be one for every 40 cy of concrete placed per hour, with a minimum of two vibrators in use
at all times, and equally spaced across the placement front. One additional vibrator shall be available for
use as a backup.
557-3.06 Cold Joints. “Cold Jointing,” the bonding of fresh concrete to set concrete, shall be done
where indicated in the contract documents, or where approved by the DCES.
A. Horizontal Joints. Within 24 hours of the start of the placement, the hardened concrete shall have
laitance and dirt removed by a high-pressure water wash. The high-pressure water wash shall be
sufficiently strong to remove any laitance and dirt, but not damage the reinforcement or reinforcement
coating. The pressure wash equipment shall be capable of providing pressure of 3000 to 5000 psi.
After pressure washing, the concrete shall be continuously wetted for a minimum of 12 hours
immediately prior to deck placement. Before placing fresh concrete, all standing water shall be
removed with oil-free compressed air. The surface shall be protected from drying to maintain a
clean, saturated surface dry condition when placing the new concrete.
If the tops of precast/prestressed elements have been sealed with a penetrating sealer, pressure
wash the tops a maximum of 2 hours prior to concrete placement. The requirement for prewetting is
waived.
B. Construction Joints. The requirements of § 555-3.06 A. shall apply. Construction joints shall
be placed only where shown in the contract documents or where permitted by the DCES.
In the event an ongoing placement is delayed excessively, the establishment of a bulkhead shall
be required.
282 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
557-3.07 Finishing Integral Wearing Surfaces on Superstructure Slabs. Machine finishing shall be
used throughout all superstructure concrete placement operations with the exception of areas which are
inaccessible to finishing machines.
Machine finishing shall be accomplished with an approved power-driven, one-operation (strike-off
and finishing) machine. The finishing machine shall have a strike-off auger set 1/4 to 1/2 inch above the
finished surface, a power-driven roller or oscillating type screed, and a pan float.
Finishing machines shall be equipped with adjustable strike-off and finishing screeds, the bottom
surfaces of which shall be adjusted to produce the required contour of the finished surface. Machines
shall be kept in true adjustment. Machines out of adjustment shall not be used until proper adjustments
have been made and the adjustments have been approved by the Engineer.
The specific method and equipment that the Contractor proposes to use for finishing will be supplied
during the Preplacement Meeting and will be subject to approval by the Engineer based on the above
listed requirements.
Finishing machine rail supports shall be accurately set and of substantial construction so that the
finished deck surface will conform to the profile and transverse sections shown in the contract
documents. Finishing machine rail supports shall be placed and adjusted to properly provide for the
deflection of forms, falsework, and structural supporting members which will occur during the placement
of the concrete. Finishing machine rail supports shall not be attached by welding to portions of flanges
subject to tensile stresses. The finishing machine rail supports shall be spaced at a maximum of 2 feet on
center. During stage construction, the support system shall be on the stage being placed.
Where the deck surface falls outside the fascia stringer flange, the finishing machine rail supports
shall be placed on the forms. The forms shall be designed to take these loads through the use of
outriggers or some other approved means.
Prior to commencing concreting operations, the finishing machine shall be given a test run over the
full length of the superstructure segment to be paved, with the finishing machine adjusted to its finishing
position. While operating the finishing machine during this test, the finishing machine rails shall be
checked for deflection and proper adjustment, the cover on slab reinforcement measured, and the
controlling dimensions of slab reinforcement and forms checked. All necessary corrections shall be
made and verified by the Engineer before concreting is begun.
A sufficient amount of concrete equal to the finishing machine capacity shall be supplied at all times.
After the concrete has been placed, spread, and consolidated to provide a uniformly dense structural
slab, the surface shall be struck off immediately by a single passage of the transverse finishing machine.
The finishing machine shall carry sufficient concrete in front of the screed to fill low and porous places.
This operation shall be done only once and shall produce a uniformly consolidated dense smooth surface
of the required contour. The passage of the strike-off auger shall provide a concrete surface slightly
above grade so that after settlement, if any, and the disappearance of excess water from the surface, the
passage of the finishing screed will result in a uniform surface at the required grade and contour over its
entire area, and provide the required cover over reinforcing.
In areas which are inaccessible to finishing machines, use of approved manual vibratory equipped
power screeds may be used, with written approval of the DCES.
Hand finishing shall be allowed only in areas inaccessible to finishing machines or manually driven
vibratory-equipped power screeds. Hand finishing shall be performed in the same sequence and manner
as machine finishing, unless otherwise permitted by the Engineer. Hand finishing shall be performed in
such a manner as to produce a concrete surface with quality and uniformity identical to that produced by
the finishing machine. Hand screeds or bullfloats shall be magnesium and 10 inches, or more, in width.
Care shall be taken not to overwork the concrete surface during any finishing operation.
In the event the placement is delayed as a result of equipment breakdowns or delivery problems, all
concrete in place shall be protected from evaporation by covering the surface with wet burlap, curing
blankets, or plastic sheets. Excessive delays shall require the establishment of a bulkhead and the
ceasing of the placement.
283 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Prior to texturing, the finished concrete surface shall be examined by the Contractor and the Engineer
using a straightedge. The straight-edge shall not be less than 10 feet long. It shall be furnished by the
Contractor and maintained in good, usable condition at the placement site at all times. While the concrete
is still plastic, surface depressions shall be filled with concrete of the same class as the placement in
progress. Surface irregularities greater than 1/4 inch in 10 feet in either the longitudinal or the transverse
direction shall be corrected in a manner acceptable to the Engineer. Thin mortar or laitance, which may
have accumulated ahead of the finishing machine screed, shall be removed from the work site. They shall
not be used to fill depressions.
After finishing, the surface shall be given a suitable texture with an artificial turf drag made of
molded polyethylene with approximately 53,500 synthetic turf blades per square yard, each
approximately 1/2 inch long. The artificial turf drag shall be of a type and brand appearing on the
Department's Approved List.
The Contractor may apply texture in a transverse direction, longitudinal direction, or parallel to the
finishing machine. Once begun, the direction of texturing shall not change. All texturing shall be done
from a work bridge immediately following the finishing operation. Texturing shall be done prior to the
beginning of curing operations. Only one pass of the turf drag over the finished area will be permitted.
If texturing is done in a transverse or skewed direction, the Contractor shall texture by hand methods
immediately after finishing machine passage.
If texturing is done in the longitudinal direction the turf drag shall be a seamless strip and shall be
attached to the work bridge such that the surface of the concrete is textured immediately after finishing
machine passage. Small areas, otherwise inaccessible to the attached drag, may be textured by hand
methods. Texture resulting from the drag shall stop within 1 foot of curbs.
The finishing movement and resulting progress of the turf drag shall be done in a manner so as to
prevent ridges or gouges forming in the concrete surface. The drag shall be weighted and the contact
area changed as required to produce an acceptable texture. The drag shall be cleaned periodically to
remove all hardened concrete particles.
557-3.08 Finishing Integral Wearing Surfaces on Structural Approach Slabs. The requirements of
§557-3.07 shall apply together with the following:
The Contractor may use an approved, manually driven, vibrator-equipped power screed in lieu of a
power-driven transverse finishing machine. Only screed model types appearing on the Department's
Approved List shall be employed for this work. The Engineer may require the use of a power-driven
finishing machine if satisfactory results are not being attained.
557-3.09 Finishing Surfaces to be Overlaid with Portland Cement or Asphalt Concrete.
Machine finishing shall be used throughout all superstructure concrete placement operations, with
the exception of areas which are inaccessible to finishing machines. In areas which are inaccessible to
finishing machines, use of approved manual vibratory equipped power screeds may be used, with written
approval of the D.C. E. S.
Surfaces shall be finished to a surface tolerance of 3/8 inch in 10 feet. The surface tolerance shall be
verified by the Engineer with an approved straightedge not less than 10 feet long. The straightedge shall
be furnished by the Contractor who shall maintain it in good condition at the paving site at all times.
Hand finishing shall be allowed only in areas inaccessible to finishing machines or manually driven
vibratory-equipped power screeds. Hand finishing shall be performed in the same sequence and manner
as machine finishing, unless otherwise permitted by the Engineer. Hand finishing shall be performed in
such a manner as to produce a concrete surface with quality and uniformity identical to that produced by
the finishing machine. Hand screeds or bullfloats shall be magnesium and 10 inches, or more, in width.
Care shall be taken not to overwork the concrete surface during any finishing operation.
Upon completion of screeding, surfaces which will be overlaid with portland cement concrete shall
be textured to conform to §557-3.07.
284 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
557-3.10 Sidewalk and Safety Walk Finish on Bridges. Sidewalks and safety walks shall be
constructed by placing concrete continuously to an elevation slightly higher than shown in the contract
documents. The concrete shall then be screeded to the correct elevations and worked with a magnesium
float to give uniform surface. Floating shall be kept to a minimum, consistent with the desired finish, in
order to avoid overworking the concrete. Follow floating with a broom finish. Surface scoring will not
be permitted.
FIGURE 557-1 STRUCTURAL CONCRETE EVAPORATION RATE
To use this chart:
1. Enter with air temperature, move up to relative humidity.
2. Move right to plastic concrete temperature.
3. Move down to wind velocity.
4. Move left to read approximate rate of evaporation.
557-3.11 Curing. After finishing and plastic-concrete texturing operations are completed, the concrete
surface shall be completely covered with clean, prewetted burlap. The allowable time period for wet
burlap covering shall not exceed five minutes from the completion of texturing, and 30 minutes from the
time of concrete placement. Care shall be taken so as not to damage the finished surface and texturing.
285 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
The curing shall not be delayed beyond the specified period. Burlap shall be lapped a minimum of 1 foot.
Lapped edges are not required to be sealed. Burlap shall be thoroughly saturated over its entire surface
area and shall be drained of excess water prior to its application. Burlap shall be kept continuously wet,
commencing 10 minutes from the time the wet burlap is placed, and protected from displacement. The
Contractor may cover the wet burlap and soaker hoses only if it is necessary to maintain curing
temperature.
The curing period shall begin only after all concrete for a given placement is complete. A curing day
is defined as any day during which the ambient air temperature at the concrete surface is 45°F or higher
for the entire day.
Conditions may occur which prevent an entire day from qualifying as a curing day, but do not
prevent portions of that day from reaching temperatures that qualify as curing temperatures. If these
conditions occur and with the Engineer's approval, the Contractor may aggregate curing hours. A curing
hour is defined as any hour during which the curing temperature remains at, or above 45°F.
An aggregation of 24 curing hours will be credited as one curing day. Aggregations of less than 24
curing hours will not be credited.
Curing hours will be determined with continuous recording thermometers. The number and
placement of the thermometers will be determined by the Engineer. Thermometers used to monitor
curing temperatures shall consist of the following types:
1. Continuously Recording Thermometer. The thermometer shall be capable of continuously recording
temperatures within a range of 0°F to 120°F for a minimum of 24 hours.
2. Maximum - Minimum Recording Thermometer. For all placements the thermometer shall be capable
of recording maximum and minimum temperatures in a range of 0°F to 120°F.
The curing temperature of concrete is the air temperature at the concrete surface, or the air
temperature between the concrete surface and its protective covering. Temperatures at these locations
are critical for proper concrete curing. For the purposes of this section the temperatures at the foregoing
locations shall be maintained between 45°F and 85°F inclusive.
A. Superstructure Slabs. After the burlap placement has been fully completed, the concrete surface shall be cured for 14 curing days. The Contractor may use either option listed below. After seven curing days, the Contractor may be permitted to perform incidental work on the structure under the loading limitations of §557-3.14 Loading Limitations for Superstructure Slabs. The burlap may be displaced in limited areas, for short durations, to perform items such as sawcut grooving, placement of sidewalks, safety walks, curbing, bridge rail, and fencing. The amount of burlap displaced to perform these operations shall be limited to the immediate area affected by the Contractor’s operations. All concrete surfaces exposed during these operations shall be kept in a saturated condition. Immediately after the work is completed in the affected area, all burlap shall be replaced for the duration of the curing period. Removable forms shall remain in place until the minimum curing period is complete. HPIC Concrete curing requirement is seven days.
1. Fourteen-Day Continuous Wetting. Leave all burlap in place for 14 curing days. Provide
continuous, uniform wetting for the entire curing period.
2. Wet Burlap and Curing Covers. Provide continuous uniform wetting for seven curing days.
After seven curing days, either of the following methods may be used:
a. Remove all burlap after seven curing days. Apply curing covers immediately upon burlap
removal. Plastic-coated fiber blankets are not required to be laid dry. Application and
maintenance of covers shall be in accordance with §555-3.08A General. Concrete cured in this
286 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
manner shall not be exposed to the atmosphere for more than 10 minutes between burlap removal
and curing cover placement.
b. Apply curing covers directly over the wet burlap. Plastic-coated fiber blankets are not
required to be laid dry. Application and maintenance of covers shall be in accordance with §555-
3.08A General. The concrete surface shall be inspected periodically to ensure that its condition
remains saturated.
The Contractor shall inform the Engineer of the intended curing procedure at the
Preplacement Meeting.
B. Structural Approach Slabs, Curbs, Sidewalks and Safety Walks on Bridges. After the burlap
placement has been fully completed, leave all burlap in place for 7 curing days. Provide continuous,
uniform wetting for the entire curing period. Forms for curbs, sidewalks, and safety walks shall
remain in place until the minimum curing period is complete. Forms for structural approach slabs
shall remain in place until sufficient strength is achieved to avoid damage to the concrete. After
removal of approach slab forms, the formed surfaces shall be cured as per the requirements of §555-
3.08A.
557-3.12 Provisions for Concreting in Cold Weather. Cold-weather concreting provisions shall apply
when the ambient air temperature below 45°F for 24 consecutive hours, or drops below 32°F at any time,
during the curing or drying periods of the concrete.
When cold-weather concreting of superstructure slabs is progressed, curing shall be maintained in
accordance with §555-3.08C Provisions for Curing in Cold Weather, except as modified here:
A. Superstructure Slabs. The curing duration shall be 14 days (336 hours). Conditions may occur which prevent an entire 24
hour day from qualifying as a curing day, but do not prevent portions of that day from reaching
temperatures that qualify as curing temperatures. If these conditions occur the Contractor may
aggregate curing hours. An aggregation of 24 curing hours will be credited as one curing day based
on the Engineer’s acceptance of monitored temperature data. Any aggregations of less than 24 curing
hours will not be credited as a curing day. A curing hour is defined as any hour during which the
curing temperature remains at, or above 45°F. Curing temperature is defined as the temperature of
the air measured at the surface of the curing concrete.
Curing temperatures shall be maintained in accordance with the requirements of Table 555-2,
Cold Weather Curing Requirements. If ambient air temperatures are expected to fall below 45°F,
materials and equipment necessary to maintain required curing temperatures shall be present on the
site or readily available. The contractor shall provide protection in a timely manner to maintain
acceptable curing.
External heat and enclosures to maintain curing temperatures may be required, as determined by
the contractors proposed curing methods documented at the Preplacement Meeting. Enclosures are
defined as those materials, combinations of materials, or systems that provide for uniform
temperature and curing management of the concrete. If enclosures are required, they shall be
constructed in such a way that all surfaces of the fresh concrete shall be maintained between 45°F and
80°F for the curing period. On structures where bottom formwork is not required, the existing
superstructure materials may be considered for their insulating values provided all curing temperature
requirements are maintained. If the Contractor expects to, or will, perform work when ambient
temperatures are below 45°F, the enclosure shall be constructed in such a manner that work can be
performed inside the enclosure without exposing any concrete to a temperature below 45°F. All
concrete surfaces within heated areas shall be protected from drying by the use of live steam or use of
continuously wetted burlap. All concrete surfaces within heated areas shall be protected from surface
287 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
disintegration of fresh concrete due to an accumulation of carbon dioxide gas by properly venting the
enclosure or use of non-combustion type heating systems.
Continuously recording thermometers shall be placed on both the top and underside of the deck to
monitor areas where extreme cold or heat can be expected. Multiple thermometers may be required
as directed by the Engineer. On structures where bottom formwork is not required and the existing
superstructure materials are considered for their insulating value, temperatures shall be monitored at
the interface between the existing superstructure materials and new concrete using continuously
recording thermocouples and thermometers.
A maximum temperature differential of 30° F between any two locations within any form of
enclosure, heated or otherwise, shall be maintained at all times.
When the ambient temperature is 45°F or greater, an enclosure may be removed for access to
progress additional work providing there is a temperature difference of 30 Fahrenheit degrees or less
between the air and the surface of the concrete. If the temperature difference between the air and the
surface of the concrete is greater than 30 Fahrenheit degrees, temperatures shall be gradually reduced
at a rate not to exceed 1°F /hr until the temperature difference is equal to or less than 30 Fahrenheit
degrees. If an enclosure is removed, all heating in other areas shall cease until such time that the
enclosure is replaced. Upon completion of the incidental work and replacement of the enclosure, the
Contractor shall reestablish acceptable curing temperature differentials, with a maximum temperature
differential not more than 30 Fahrenheit degrees between any two locations within the enclosure.
After seven (7) curing days, the Contractor may perform work on the structure to complete
sidewalks, safety walks, curbs, and barriers. Work shall progress only when ambient temperatures
are 45°F or greater or within an enclosure as described above. Incidental work shall not cause
damage to the structure.
For all incidental work, the requirements of §557-3.14, Loading Limitations for Superstructure
Slabs, shall apply.
B. Structural Approach Slabs, Curbs, Sidewalks and Safety Walks on Bridges.
The provisions of 557-3.12 A Superstructure Slabs shall apply except the curing duration shall be 7
days (168 hours). After three (3) curing days, the Contractor may perform work on approach slabs to
complete sidewalks, safety walks, curbs, and barriers. Work shall progress only when ambient
temperatures are 45°F or greater or within an enclosure as described above. Incidental work shall not
cause damage to the structure.
For structural approach slabs, the requirements of §557-3.15 Loading Limitations for Structural
Approach Slabs, Sidewalks, and Safety Walks on Bridges, shall apply.
C. Saw Cut Grooving.
When concrete is placed, cured, or dried under cold weather provisions, and a surface treatment
option requiring saw cut grooving is used, saw cut grooving may be commenced after 7 curing days
and shall be completed prior to commencing the drying period. Work shall progress only when
ambient temperatures are 45°F or greater or within an enclosure as described in §557-3.12 A. Care
shall be taken to prevent damage to the structure and no chipping or spalling of concrete shall occur at
the sawcut edges.
D. Winter Surface Treatment - Superstructure Slabs and Structural Approach Slabs.
Upon completion of the curing period, the Contractor shall progress one of the following two options:
1. Option 1. The top surface and fascias of the superstructure slab shall be air dried for 10
days before being sealed with a penetrating sealer or exposed to freezing temperatures. Saw cut
grooving shall be completed, as described above, prior to application of penetrating sealer.
External heat and enclosures to maintain drying temperatures may be required. Drying shall be
achieved by the following:
288 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
a. Providing free air flow and maintaining temperatures between 45°F and 80°F to the top
surface and fascias (vertical faces) of the superstructure slab. Fascia forms shall be removed
to allow for free air flow.
b. Drying of the underside of the structure, and of the fascias when a concrete barrier is to be
placed on the superstructure slab, will not be required. However, ambient temperatures shall
be maintained between 45°F and 80°F in these areas for the duration of the drying period.
c. The drying period shall be continuous except that aggregate drying hours may be allowed
when a contractor ceases free air flow for any reason but protects the drying concrete from
exposure to any additional water. Exposure to any additional water, beyond minor leakage
thru an enclosure in limited areas, will require the drying period to re-commence for 10 days.
Any 3 hour period of time, or fraction thereof, when the concrete is exposed to minor leakage
shall not be counted as part of the drying period. Minor leakage shall be defined as water that
dries or evaporates in 3 hours or less. Limited areas are defined as areas less than 100 ft2.
The total area of allowable minor leakage shall not exceed 5% of the concrete area under
drying conditions. The same area of concrete shall not be exposed to minor leakage more
than twice. Areas that exceed 100 ft2 or are exposed to additional water that does not dry or
evaporate in less than 3 hours, may be dried independently to accommodate removal of the
original enclosure. Any independent enclosures shall be maintained under the same
temperature and air flow requirements as the original enclosure for 10 days.
d. Means of accelerating the drying process will be considered by the Director, Materials
Bureau, to achieve an internal moisture content of 85% relative humidity or less, measured at
a depth of 1 inch from any concrete surface.
Once the drying period is complete, temperatures shall be gradually reduced at a rate not to
exceed 1°F/hr until the temperature within the enclosure equals the temperature outside the enclosure.
Application of a penetrating sealer, in accordance with other items shall be completed before opening
the superstructure slab to traffic.
2. Option 2. The top surface and fascias of the superstructure slab shall be air dried for 24
hours before being sealed with an interim application of penetrating sealer or being exposed to
freezing temperatures. No saw cut grooving will be performed. External heat and enclosures to
maintain drying temperatures may be required. Work shall be progressed by doing the following:
a. Providing free air flow and maintaining temperatures between 45°F and 80°F to the top
surface and fascias of the superstructure slab. Fascia forms shall be removed to allow for free
air flow.
b. Drying of the underside of the structure, and of the fascias when a concrete barrier is to
be placed on the superstructure slab, will not be required. However, ambient temperatures
shall be maintained between 45°F and 80°F in these areas for the duration of the 24 hour
drying period. Application of interim penetrating sealer shall be completed before opening
the superstructure slab to traffic.
c. After April 1st the contractor shall clean the deck of debris and provide necessary site
access. The Department will inspect the superstructure slab for freeze / thaw or scaling
damage. Damage shall be defined as:
(1) Delaminations
(2) Surface defects as follows:
289 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
• Total combined area greater than 50 ft2 with a scaling rating of 3 or greater as
defined by ASTM C-672.
• Total combined area greater than 10 ft2 where the surface distress is greater than
3/16 inch deep.
(3) Pop-outs – surface imperfections greater than 3/4 inch in diameter
d. If the above described damage exists, the Contractor shall repair any damaged or
defective concrete greater than 3/16 inch deep by saw cutting the perimeter of the area to a
depth of 3/4 inch, chipping any unsuitable material to 1-1/2 inch or sound concrete
(whichever is deeper) with light, hand held, pneumatic tools, at a 45 degree angle into the
repair area. Clean all repair area surfaces thoroughly by blast cleaning. Repair small areas 3
ft2 or less using approved concrete repair material that provides a permeability less than 1200
coulombs, Item 701-04, preparing the surface according to the material manufacturer’s
recommendations. Repair larger areas using Class DP concrete, preparing the surface
according to §584-3.02 and 584-3.03. Cure Class DP concrete for 7 days.
e. After all necessary repairs are completed, the Contractor shall perform diamond grinding
to the entire superstructure slab and approach slabs, to within 1 foot of any curb or barrier.
Diamond grinding shall be performed as follows:
(1) The depth of the grinding shall be approximately 3/16 inch to obtain a smooth texture.
(2) In all travel lanes, use equipment having gang-mounted diamond saw blades on a
multi-blade arbor specifically designed for PCC pavement or superstructure production
grinding. Using equipment capable of producing a 3 ft wide (minimum) grinding pass that
is equipped with a vacuum system capable of removing slurry from the bridge deck
surface, such as the Target 3800, Boart-Longyear (Kushion Kut) PC5000 or PC600, or
equal as approved by the Director, Materials Bureau. Smaller diamond grinding equip
shall be used as necessary to complete grinding adjacent to curbs or barriers. The
Contractor shall submit requests to use other equipment at least 7 days prior to the start of
grinding operations.
(3) Begin and end diamond grinding lines normal to the bridge deck centerline. Grind the
bridge deck longitudinally such that at least 95% of the bridge deck surface is ground and
the bridge deck is in the same plane across a joint or crack when measured with a 3 ft
(minimum) straightedge. When steel joints are specified, joints shall be placed to allow
for the required grinding of 3/16 inch. Feathering of the grinding operation at steel joints
shall be kept to a minimum. Provide surface drainage by maintaining the proper cross-
slope on the finished surface and by blending adjacent passes. Regrind the bridge deck if
an acceptable surface is not being obtained.
(4) Continuously remove slurry from the bridge deck using the vacuum system on the
grinding equipment. If required, provide equipment capable of transporting the slurry
from the job site to an acceptable waste area or facility, without spilling.
(5) Traffic may be allowed on ground areas after slurry removal is complete or on decks
where only partial diamond grinding is complete.
(6) After diamond grinding is complete, concrete shall be saw cut grooved according to
contract documents and specifications for saw cut grooving, followed by penetrating
sealer application placed in accordance with contract documents and specifications for
penetrating sealers.
E. Winter Surface Treatment –Curbs, Sidewalks and Safety Walks on Bridges.
Upon completion of the curing period, concrete shall be air dried for 24 hours by providing free air
flow and maintaining temperatures between 45°F and 80°F to all concrete surfaces. The drying
period shall be continuous. Upon completion of drying, curbs, sidewalks and safety walks shall be
sealed with a penetrating sealer in accordance with contract documents.
290 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
557-3.13 Removal of Forms. Removal of forms for superstructure slabs shall meet the requirements of
§555-3.09 Form Removal and as modified herein. The minimum curing period prior to form removal is
10 curing days, except that for cold weather concreting a minimum of 14 curing days is required unless
minimum compressive strengths are achieved as determined by the D.C. E. S. A curing day is defined in
§555-3.08A. Permanent field connections, if required, shall be made on the same day prior to removal of
forms and falsework.
The following inspection procedures will be used as a check to insure the soundness of the concrete
structural slab adjacent to the steel forms. Not less than two days after completion of a concrete
structural slab pour, but prior to the next slab pour, the Contractor shall remove a section of the steel
form from the most recently completed pour of each span, at a location selected by the Engineer, in order
to provide visual evidence that the concrete mix or the construction procedures are obtaining the desired
results. If either the concrete mix or the construction procedures are varied significantly within a pour,
such as a change in the extent of vibration or change in the workability of the mix, the Contractor shall
remove another section of form to verify that the new procedures yielded desirable results.
After the concrete has been placed in a span for a minimum of ten days but prior to any further work
performed on the superstructure in that span, the Engineer will spot-check the underside areas of the steel
forms by sounding with a suitable-weight hammer at least 50% of the area of at least 25% of the
individual form panels on a random basis to determine whether any honeycomb or void areas exist. If
such areas are detected, the Contractor shall remove the forms from these areas for a visual inspection of
the slab.
The amount of sounding and form removal may be reduced after a substantial amount of slab has
been constructed and inspected, if the Contractor's methods of construction and the results of the
inspections as outlined above indicate that sound concrete is present throughout the slabs.
If, after removing a section of form, the concrete is found to be defective, additional panels shall be
removed. All defective concrete shall be repaired to match the adjacent concrete in section and color.
The form sections shall be removed by a metal saw or air-carbon-arc gouging with minimum damage
to the concrete. Cuts shall only be sufficiently deep to sever the form. Any other method of removal
shall be submitted to the Deputy Chief Engineer (Structures) for approval. Cuts that are parallel to the
corrugations in the forms shall be located on the sloping surface midway between a crest and a valley.
Cuts parallel to the supporting beams shall be made through the supporting angles taking care not to
damage the structural steel beams. The Contractor will not be required to replace the removed forms.
The Contractor shall provide all the facilities required for safe, suitable and convenient means of
access to the forms for the Engineer’s inspection.
557-3.14 Loading Limitations for Superstructure Slabs. Superstructure slabs, during the curing
period, may be subjected to a vehicle load not to exceed 10 tons, or a wheel load not to exceed 3 tons no
sooner than seven curing days after placement. Full legal loading may commence using either of the
following options:

560-3.02 Dimension Stone Masonry. The provisions of §560-3.01 shall apply with the following
additional requirements:
A. Preparation of Stone and Bed. Each stone shall be cleaned and thoroughly saturated with water
before being set. The bed which is to receive the masonry shall also be cleaned and moistened.
B. Bedding of Stone. All stone shall be well bedded in mortar and settled in place with a suitable
wooden maul before the setting of the mortar.
C. Spalls not Permitted in Mortar Beds. No pinning up of stones with spalls will be permitted, and
no spalls will be permitted in beds.
D. Expansion Joints. All surfaces of stone in contact with expansion joint material shall be made
smooth, unless otherwise shown on the plans. The joints shall be filled with premolded resilient joint
filler and sealed with an approved joint sealer as shown on the plans, or as ordered by the Engineer.
All joints in concrete backing shall be protected against intrusion of water into or through the
joint by the installation of an approved water stop. The water stop shall be embedded into the
concrete at least 3 inches on each side of the joint and shall be installed as near to the inside face of
the concrete backing as practicable. The water stop may be of ASTM B370, 20 ounce preformed
copper strip, 0.025 inch minimum thickness, soldered to be water tight and continuous, or may be
approved flexible water stop as shown on the plans. Water stops shall be manufactured and installed
so as to provide for the expansion and contraction movements present at the joint.
In case any stone is moved or the joint broken, the stone shall be taken up, the mortar thoroughly
cleaned from beds and joints, and the stone reset in fresh mortar.
Joints shall not be filled by pouring in a thin or liquid mortar.
E. Pointing (new construction) and Tuck Pointing (raking out and repointing).
1. Pointing. Tool the face joints with a pointing tool before the mortar sets, as approved by the
Engineer. Avoid smearing the masonry surfaces with excess mortar forced out of the joints. For
joints not pointed when the masonry is laid, prepare the joints for pointing by following the tuck
pointing procedures. There will be no separate payment for this work.
2. Tuck Pointing (Repointing). Repoint the joints in masonry where indicated on the Contract
plans or directed by the Engineer. Use an Item 705-21 Type M, S or N masonry or mortar
cement, tuck pointing mortar (or a specially designed one) with the same or weaker strength than
the original mortar, as approved by the Engineer.
Remove soft, loose, cracked and deteriorated mortar to a minimum depth (measured from the
wall face) of twice the average joint width, and remove all deteriorated mortar beyond the
minimum depth, as ordered by the Engineer. Do not damage the masonry during the removal
process. Clean all contamination from the prepared joints.
Prior to repointing, flush with water and leave all surfaces to be re-mortared in a dampened,
surface dry state. Pack the prepared joints in layers with mortar that closely matches the original
color and texture, allowing each layer to become thumb-print hard before the next. Use at least
two layers when the joint depth is twice the joint width. Apply a final layer thickness that does
298 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
not exceed the joint width. When the final layer is thumb-print hard, finish with a pointing tool
that recreates the original joint shape, or as approved by the Engineer.
Perform pointing when the ambient temperature is 40°F or above, and the masonry is frost
free. Avoid recessed joints that hold water.
After the mortar sets, clean all mortar and cement stains from other surfaces. In direct
sunlight, keep the newly pointed masonry moist for at least 3 days. In shade, moisten 2 to 3 times
a day for at least 3 days.
F. Drawings. The contract plans show the general character of the masonry. Prior to the beginning
of any work, the Contractor shall prepare and submit for the approval of the Regional Director, three
sets of detail plans for all dimension masonry shown on the plans. The Contractor shall carefully
check and assume full responsibility for the accuracy of this work. These detail plans will be
examined and either approved or returned without approval to the Contractor, who shall check the
indicated corrections and resubmit two sets of prints of revised details. When the detail plans have
been approved, the Contractor shall furnish the Regional Director with three sets, one of which shall
be reproducible. The drawings shall conform to the size and type of requirements for Shop Drawings
set forth in the New York State Steel Construction Manual.

feet high of approved units and matching mortar at a location designated. This procedure shall be
repeated until a sample wall is approved by the Engineer. The approved sample wall shall be
maintained intact until the Engineer directs its removal.
In lieu of the field sample wall, the Contractor may show, for approval, a building constructed
with units of the same type, color, texture and surface finish required. The field sample wall shall be
required if the building masonry is not approved.
Upon approval of the sample wall or building, the Contractor shall furnish and lay split masonry
to conform with the approved sample wall.
B. Protection and Handling. Split faced concrete masonry units shall be protected by a wrapping of
4 mil polyethylene, and shall be handled on pallets by mechanical means, or by hand or tongs.
Dumping of the masonry units from trucks, wheel barrows or other conveyances is prohibited.
Particular care shall be taken to protect all edges and the face of the masonry units. Distorted,
laminated, checked or cracked masonry units will be rejected and removed from the site of
construction.
On delivery to the site, the masonry units shall be neatly piled off the ground, on pallets or other
approved implements, and protected from moisture by wrapping them with 4 mil polyethylene.
Masonry units which become wet, shall not be laid in the wall until their conformance with the
specifications for §704-10 is shown by tests. The cost of these tests shall be borne by the Contractor.
C. Laying. The split faced concrete masonry shall be laid up, in the pattern shown on the plans, by
skilled masons and in a first-class manner. The masonry shall be laid true to line and grade in level
horizontal beds and be properly anchored. Each masonry unit shall be laid in a full mortar bed and in
a manner to form a full end joint in one operation. The space between the split face masonry and the
supporting concrete shall be filled with mortar and rodded until the mortar rises to the top of the
masonry unit as each unit is placed.
299 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
D. Bonding. The split faced concrete masonry shall be bonded to the supporting concrete. Dovetail
anchors shall be continuous, set vertically and spaced on centers not exceeding 1 foot on the concrete
walls. Ties shall be installed in the anchor slots at a maximum vertical height of 1 foot on centers.

specified. The joints shall be 3/8 inch wide and the concave jointing shall be 1/8 inch deep at the
center.
F. Protection Against Weather. The split faced concrete masonry shall be protected against the
action of the weather. The tops and at least 2 feet down the sides of all walls not completed shall be
constantly protected with suitable waterproof covering properly secured in place during periods of
suspended work. The facing shall be so protected until it has been bonded to the concrete wall and
completely sealed against moisture. During hot dry weather, the masonry shall be protected from the
sun and kept moist for at least three days after completion.
G. Protection Against Damage. Projections and angles exposed to damage shall be boxed or
otherwise protected to prevent damage. Any units damaged during the progress of the work shall be
replaced with new units at the Contractor's expense.
H. Cleaning of Exposed Faces of Mortar and Drippings. Exposed faces of split faced concrete
masonry units shall be cleaned free of excess mortar and mortar drippings, as the work progresses, to
prevent excessive rubbing during final cleaning operations.
I. Expansion and Contraction Joints. Expansion and contraction joints shall be constructed as
shown on the plans. The surfaces of the joints shall be plumb, true to line and smooth to the caulking
compound.
J. Final Cleaning. After the completion of adjacent work likely to soil the masonry, the split faced
concrete masonry shall be thoroughly cleaned, removing all dirt, dust, mortar, stains, etc. The
concrete masonry shall be brushed, while dry, with stiff fiber brushes. If this brushing does not clean
the masonry to the satisfaction of the Engineer, then the Contractor shall clean the facing with soap
powder in clean water applied with stiff fiber scrub brushes. After scrubbing with soap and water the
Contractor shall rinse the masonry with clean water. The Contractor may, with the Engineer's
approval, substitute a cleaning solution that will not harm the concrete or mortar joints. The cleaning
operation shall in all cases start at the top and proceed downward.
K. Caulking. When the split faced concrete masonry has received the final cleaning, all expansion
and contraction joints shall be filled at least 1 inch deep with caulking compound.
All surfaces to receive the caulking compound shall be clean, free of loose materials, dirt, dust,
frost, moisture, oils, laitance or curing compounds and shall be primed with clear lacquer, shellac or
the manufacturer's recommended primer after the surfaces have been cleaned. A bond breaker shall
be used as a release material back of the caulking compound. The bond breaker may be polyethylene,
specially treated bond inhibiting pressure sensitive tape or any approved equal. The caulking
compound shall be tooled with a concave joint finishing tool to provide a neat smoothly finished joint
of uniform width. Where solvents are required on the jointing tool, they shall be as recommended
by the manufacturer of the caulking compound.

1. General
a. The centerline of sole plates or fixed portions of bearing assemblies attached to the structural
steel shall not be offset from the centerline of bearing stiffeners or diaphragm connection plates
by more than one-half the thickness of the flange at that location, or the thickness of the bearing
stiffener or connection plate, whichever is the lesser distance.
b. The bearing shall be cleaned and regreased with automotive grease at the time of installation.
2. Fixed. No additional requirements apply.
3. Expansion. These may vary from perfect alignment. Therefore, expansion bearings shall be
set in accordance with the following.
a. Type S. R. Bearings
(1) The bearing shall be set vertical under full dead load at an ambient temperature of 68 F.
(2) The maximum variation from perfect alignment is a function of the bearing height. The
bearing height is the distance between the upper and lower contact surfaces of the movable
portion of the bearing. For bearings with a height of 20 inches or less, the maximum
variation from perfect alignment, taking into account the effect of temperature and load at the
time of measurement, shall be calculated by the following formula:
M = ± (1/2 inch + (L/14,000 ) )
where “M” = maximum variation from perfect alignment measured as the horizontal
distance between the centerline of the cap plate and the centerline of the masonry plate in
inches and “L” = total expansion length in inches between the centerline of the movable
bearing being considered and the centerline of the fixed bearing, from which motion must
progress. Such variations shall not exceed 1 inch offset, or a five degree rotation of the
movable portion of the bearings from the required alignment, whichever is less.
The maximum variation of all bearings having a height exceeding 20 inches shall be
approved on an individual basis by the DCES.
(3) No bearing adjustments shall be made until the completed structural slab has been in place
for at least seven curing days. Any adjustments needed to meet the above requirements may
require jacking the superstructure. All adjustments shall be accomplished according to a
written procedure submitted by the Contractor for DCES approval. All adjustments shall be
made at no additional cost to the State.
b. Type S. S. Bearings
(1) The sliding plate shall be centered on the masonry plate under full dead load at an ambient
temperature of 68 F.
(2) The maximum variation from perfect alignment between the centerlines of the fixed and
movable portions of the bearing device, taking into account the effect of temperature and load
at the time of measurement, shall not exceed plus or minus 1/2 inch longitudinally. This
variation shall be measured as the horizontal distance between the centerline of the sliding
314 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
plate and the centerline of the masonry plate. The movable portion of the bearing device
shall be fully supported by the fixed portion under all temperature and loading conditions.
(3) No bearing adjustments shall be made until the completed structural slab has been in place
for at least seven curing days. Any adjustments needed to meet the above requirements may
require jacking the superstructure. All adjustments shall be accomplished according to a
written procedure submitted by the Contractor for DCES approval. All adjustments shall be
made at no additional cost to the State.
B. Type M.R. Bearings
1. General. The centerline of sole plates or other fixed portions of bearing assemblies attached to
the structural steel shall not be offset from the centerline of bearing stiffeners or diaphragm
connection plates by more than one-half the thickness of the flange at that location, or the
thickness of the bearing stiffener or connection plate, whichever is the lesser distance.
2. Fixed. No additional requirements apply.
3. Expansion. These may vary from perfect alignment. Therefore expansion bearings shall be
set in accordance with the following:
a. The sliding plate shall be centered on the masonry plate under full dead load at an ambient
temperature of 68 F.
b. The maximum variation from perfect alignment between the centerline of the fixed and
movable portions of the bearing device, taking into account the effects of temperature and load at
the time of measurement, shall not exceed plus or minus 1 inch longitudinally unless otherwise
indicated on the plans. This variation shall be measured as the horizontal distance between the
centerline of the sliding plate and the centerline of the masonry plate.
c. No bearing adjustments shall be made until the completed structural slab has been in place for
at least seven curing days. Any adjustments needed to meet the above requirements may require
jacking the superstructure. All adjustments shall be accomplished according to a written
procedure submitted by the Contractor for DCES approval. All adjustments shall be made at no
additional cost to the State.
C. Type E.P. and Type E.L. Bearings
1. General
a. These bearings are designed to function properly provided that minimum distortion occurs
along the beam axis under full dead load at an ambient temperature of 68 F. Elastomeric
bearings shall be installed when the ambient temperature is between 40 and 80 F inclusive. The
Contractor may elect to install the bearings when the ambient temperature is outside of the
allowable range, provided the Contractor submits, and receives DCES approval, of an installation
procedure that either resets the bearings when the temperature is in the allowable range or
deforms the bearings so that they perform as if they were installed at 68 F.
b. For prestressed concrete superstructures, the bearing shall be anchored to establish the fixed
end of the bridge as soon as possible after stringer erection. For adjacent prestressed box beams,
or prestressed slab superstructures, the anchorage shall be completed prior to filling the shear
keys. The method of anchorage shall be in accordance with the details shown on the plans.

All mechanical devices, supplied by the Joint System manufacturer, used to set the joint system to
the proper width, will remain the property of the Manufacturer. When no longer required, the devices
shall be returned to the Manufacturer.
C. Sliding Plate. In order to perform the work of installing the joint systems in a proper manner,
some portions of the curb and parapet cannot be constructed until after the sliding plates of the joint
system are installed. This surface shall be scrubbed with wire brooms. After the surface preparation
has been accepted, every effort should be made to thoroughly wet the concrete surface, and all
porous surfaces to be in contact with new concrete, for 12 hours. If, in the opinion of the Engineer,
conditions or the situation prohibits this, then the surfaces should be wetted for as long as possible.
Construction joints must be wetted by continuous spraying with hoses using potable water. The
Contractor shall remove any puddles of free standing water with oil-free compressed air, and protect
the surfaces from drying, so the existing concrete remains in a clean, saturated surface dry condition
until placement of the new concrete.
D. Permanent Seals. After the joint system has been completely installed over the full width of the
structure, including sidewalks, the temporary seals shall be removed and replaced with permanent
seals. After the temporary seals are removed, all metal surfaces which will be in contact with the
permanent seals shall be commercially blast cleaned (SSPC-SP6) to visual standard CSP6 as defined
by SSPC Vis 1-89.
E. Final Placement. After the modular joint system has been set to its final line and grade, the recess
opening shall be filled with Class E Concrete. This surface shall be scrubbed with wire brooms.
After the surface preparation has been accepted, every effort should be made to thoroughly wet the
concrete surface, and all porous surfaces to be in contact with new concrete, for 12 hours. If, in the
opinion of the Engineer, conditions or the situation prohibits this, then the surfaces should be wetted
for as long as possible. Construction joints must be wetted by continuous spraying with hoses using
potable water. The Contractor shall remove any puddles of free standing water with oil-free
compressed air, and protect the surfaces from drying, so the existing concrete remains in a clean,
saturated surface dry condition until placement of the new concrete. The uppermost surface of the
concrete placement shall be finished in accordance with the requirements of Section 557 except that
machine finishing will not be required. The cost of this work shall be included in the unit price bid
for the slab item(s).
F. Watertight Integrity Test. After the joint system is permanently installed, including plates and all
concrete placements, a watertight integrity test shall be performed. The test shall be done in
accordance with the requirements of §567-3.01H.

335 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
C. Repair. Repair shall be made with a material acceptable under §701-04 or §701-12. Methods of
repair shall be acceptable to the Engineer. The color of the repaired portion shall match, as nearly as
practicable, the color of the surrounding concrete. Repaired portions shall exactly match shape
requirements. The repaired portion shall withstand a moderate blow from a 16 ounce hammer.
Repair shall be done at no cost to the State.
569-3.03 General: Precast Concrete. The definition of defects and the repair requirements contained in
704-03 shall apply.
569-3.04 Cast-In-Place Concrete - Constructed Forms. The requirements of Section 555 and Section
556 shall apply with the following modification:
Thoroughly wet the structural slab surface and all porous surfaces to be in contact with new concrete
for at least 12 hours immediately prior to placement. Remove all standing water with oil-free compressed
air, and protect the surfaces from drying, so the concrete remains in a saturated surface dry condition until
placement of the new concrete. If the forms are removed before seven curing days have passed, the
concrete shall be cured by means of a clear curing compound. No curing blankets will be required.
Curing compound shall be sprayed on the concrete surface immediately following the slipforming and
hand finishing operations. The compound shall be applied by means of pressure spraying or distributing
equipment at the rate directed by the Engineer, but not less than 1 gallon per 150 square feet of surface.
The equipment for applying the compound shall be such that the compound is applied as a fine spray with
no surface damage to the concrete. The equipment shall also provide adequate agitation of the compound
during application, and shall be approved by the Engineer before work is started. Should the method of
applying the compound produce a non-uniform film, or should the spraying equipment fail and duplicate
equipment not be immediately available, the application of curing compound shall be discontinued
immediately and the curing shall be accomplished by another method acceptable to the Engineer. The
Contractor shall stockpile sufficient approved coverings for protection of the concrete in the event of rain,
non-uniform film application, or breakdown of spray equipment.
569-3.05 Cast-In-Place Concrete - Slipformed. The requirements of Section 555, Section 556 and the
following, shall apply:
A. The forming of the barrier shall be accomplished by self-propelled equipment approved by the
Engineer. The requirements of 555-3.03 shall not apply. Thoroughly wet the structural slab surface
and all porous surfaces to be in contact with new concrete for at least 12 hours immediately prior to
placement. Remove all standing water with oil-free compressed air, and protect the surfaces from
drying, so the concrete remains in a saturated surface dry condition until placement of the new
concrete.
B. After all reinforcing bars have been placed, all bridge joints installed, and all other hardware
placed in the area of the barrier, the Contractor shall perform a "dry run" over the entire length of the
barrier installation location. It is necessary only to "dry run" a single day's placement during any
given day; however, the entire barrier length shall be traversed.
The "dry run" may be made with either the actual slip forming equipment, or with an exact
"mock-up" of the equipment. The "mock-up"; if utilized, shall be the exact size, shape and
dimensions of the slip forming equipment. It shall be a minimum of 4 feet long. Its movement shall
be able to be correlated with a string, or survey, line indicating the correct offset location of the
barrier.
C. After the "dry run" portion of the work has been completed and all obstructions have been cleared,
the slip-forming equipment shall be demonstrated for capability. The demonstration shall be done in
336 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
the presence of the Engineer. The Contractor shall make all adjustments, or alterations, to ensure that
the equipment has the capability to produce an acceptable product. No work shall be done without
the Engineer's approval. The capability demonstration will be required only once for each piece of
forming equipment used on the project.
D. The Engineer's approval is for equipment capability only. The Contractor shall be entirely
responsible for meeting the tolerances given under MATERIALS, 569-2.03. Fabrication Tolerances.
Sections which do not meet tolerance requirements are subject to removal and replacement at no cost
to the State, at the discretion of the Engineer.
E. Central and Transit Mixed Concrete. The provisions of 501-3.03 C and D shall apply for Central
Mixed and Transit Mixed Concrete respectively, except that water may be added to the mixture one
additional time at the point of deposition to maintain the desired slump. The water addition may be
made anytime after the beginning of discharge until approximately two-thirds of the load, as
determined by the Engineer, has been discharged. After the water addition, the concrete shall be
mixed at least 30 revolutions in the mixing range. When the water addition is made after discharge
the total number of revolutions shall not be more than 190.
Truck Mixed Concrete. The provisions of §501-3.03 E shall apply except that after initial slump
has been achieved, water may be added to the mixture one additional time to maintain the desired
slump. The water addition may be made anytime after the beginning of discharge until approximately
two-thirds of the load, as determined by the Engineer, has been discharged. After the water addition,
the concrete shall be mixed at least 30 revolutions in the mixing range.
F. Concrete supply shall be sufficient to produce a continuous, completely shaped barrier. If concrete
placement is interrupted, for any reason, the placement shall be protected from drying by several
layers of wet burlap. A construction dam, or bulkhead, shall be installed if the interruption exceeds
30 minutes. If the interruption exceeds 90 minutes, further placement shall be discontinued.
Concrete placement at this location may then resume only after 12 hours, measured from the time of
delay, has elapsed.
G. Concrete placement may begin at the joint beyond the bulkhead without time constraints. If the
length of placement between the bulkhead and the next joint is such that, in the opinion of the
Engineer, it may not be slipformed, the Contractor shall form the section by methods other than
slipforming.
H. Cold joints in the barrier, that is, joints formed due to the attachment of fresh concrete to set
concrete, shall be made in the following manner. The set concrete shall have its surface cut to
remove all loose, and otherwise unsatisfactory materials. Tools used for this purpose shall be
approved by the Engineer, prior to use. The surface shall be scrubbed with wire brooms and shall be
kept wet until new concrete is placed.
I. The Contractor shall make provisions to allow hand finishing, should it be necessary, on all
surfaces. Hand finishing, if done, shall be done immediately after the passage of the slipforming
equipment. Curing compound shall be applied only after hand finishing has been completed at any
particular location.
J. Concrete shall be cured by means of a clear curing compound in accordance with the requirements
of 569-3.04.
K. Joints and construction grooves shall be introduced at the locations indicated on the Contract
Plans. If sawcutting methods are employed the following requirements shall apply:
337 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
1. The equipment shall be demonstrated, for capability, to the Engineer.
2. No sawcuts, for any purpose, shall be made in the structural slab.
3. In order to avoid sawcuts in the structural slab, the portion of the joint 3 inches directly above the
structural slab shall be hand tooled immediately after finishing.
4. All sawcuts shall be made normal to the structural slab surface. The joints shall be sawcut as
soon as no damage to the concrete will result with a maximum time of 8 hours. The clear curing
compound shall be reapplied at the sawcut.
569-3.06 Precast Concrete
A. Immediately prior to installation, the barrier units shall be inspected for defects. Defects which
conform to the definition of minor defects as given in §704-03 shall be repaired in accordance with
the requirements of that subsection.
After the inspection for defects has been completed, the contact surface of all precast barrier shall
be sandblast cleaned in accordance with the requirements of §584-3.02A, and §584-3.02C. After
sandblasting operations are completed the surfaces shall be thoroughly vacuum cleaned.
B. After the cleaned surface has been accepted, thoroughly wet the surface over which the precast
barrier will be placed for at least 12 hours immediately prior to placing the grout bed. Remove all
standing water with oil-free compressed air, and protect the surface from drying, so the surface
remains in a saturated surface dry condition when placing the grout bed. All precast barrier shall be
installed on grout beds conforming to the requirements of §701-05 as modified herein. The exact
bedding placement requirements shall be established by the barrier system manufacturer. However,
no grout bed shall be greater than 1/2 inch in thickness after the barrier has been installed in its
permanent position. All grout bedding material shall be tooled flush with the barrier edge.
Care shall be taken to prevent grout from setting prior to barrier unit installation. If, in the
opinion of the Engineer, the grout has set, or has begun to set, it shall be removed. No retempering
will be permitted. The affected installation area shall be thoroughly cleaned of grout, by methods
acceptable to the Engineer, and new grout shall be placed, all at no additional cost. All vertical
adjustments shall be made by the addition, or removal, of grout. No wedges will be permitted.
Lifting of the barrier which, in the Engineer's opinion, will result in permanent voids occurring
between the barrier unit and the grout bed, will not be permitted.
C. Unless otherwise noted joints between units shall utilize materials required by ASTM D1056,
Grade 2B1 or 2B2 and shall be installed in the manner indicated on the approved precast barrier
system drawings.
D. Units which are damaged during installation, due to the Contractor's operations, shall be repaired,
or replaced, as determined by the Engineer. Repair or replacement shall be done at no cost to the
State.
E. Precast barrier anchored to the underlying support by means of drilled-in-bolts, may be anchored
by one of two methods:
1. Bolts chemically anchored to the underlying support. Holes drilled for this method will not
go completely through the underlying support. Bolt installations will be subjected to load testing
acceptance requirements.
2. Bolts mechanically anchored to the bottom of the underlying support. Holes drilled for this
method will go completely through the underlying support. Bolt installations will not be load
tested.

SECTION 571 - DISPOSAL OF PAINT REMOVAL WASTE (Last Revised January 2019)
571-1 DESCRIPTION. The work shall consist of managing, accumulating, packaging, labeling,
loading, transporting, treating, and disposing paint removal waste.
571-1.01 Paint Removal Waste. Paint removal waste consists of removed paint particles combined with
material used to remove the paint and any organic or inorganic materials from bridge surfaces, by either
bridge washing or blast cleaning operations, without use of any added chemical solvents. All testing of
the paint removal waste necessary to satisfy the requirements of the waste transporter or disposal facility
shall be the responsibility of the contractor.
Paint removal waste does not include used tyvek suits, respirator filters, tarpaulins or incidental trash.
These incidental wastes generated by the Contractor in completing the work are covered by §107-10
Managing Surplus Material and Waste.
352 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
A. Hazardous Paint Removal Waste Containing Lead. This shall apply to spent abrasives, coatings
and paint chips removed from steel substrates on bridges designated in the contract documents as
being lead-based. This does not include waste containing a mixture of lead and asbestos. Waste
containing a mixture of lead and asbestos shall be disposed of in accordance with Section 210
Removal and Disposal of Asbestos-Containing Material (Buildings, Bridges and Highways).
B. Non-Hazardous Industrial Solid Paint Removal Waste. This shall apply to spent abrasives and
coatings removed from steel substrates on bridges designated in the contract plans as being non-lead-
based.
571-2 MATERIALS. The Contractor shall use containers or roll-offs acceptable to the Waste Disposal
Facility. The capacity of each container shall be clearly marked on each container in an easily visible
location.
571-3 CONSTRUCTION DETAILS.
571-3.01 General. The Engineer will provide the Contractor with the Generator site identification
number(s) issued by the USEPA. All paint removal waste shall be deposited and sealed in containers or
roll-offs concurrent with generation. The paint removal waste shall be accumulated in clean, dry,
weatherproof, watertight containers or roll-offs furnished by the Contractor and shall not be left exposed
to the elements at the end of the working shift. All equipment and containers or roll-offs shall meet the
requirements of USDOT for transport.
Paint removal waste shall be accumulated, handled, packaged, documented, loaded, transported,
treated and disposed in accordance with all applicable Federal and State laws, rules, and regulations.
571-3.02 Paint Removal Waste Composition.
A. Hazardous Paint Removal Waste Containing Lead. Paint chips are known to contain lead and
the combined paint removal waste stream is therefore categorized as hazardous waste. The
Department has presumed that the waste will test as hazardous. The Contractor shall ensure that only
solid paint removal waste is deposited into the containers or roll-offs. The determination has been
made that such waste contains less than 2% by weight of organic material. Disposal facilities may
refuse to accept paint removal waste that is different than the Typical Paint Waste Composition.
Paint removal waste containing additional contaminants added by the Contractor or by the
Contractor’s operations shall be the responsibility of the Contractor. All testing of the paint removal
waste necessary to satisfy the requirements of the chosen Disposal Facility or Transporter shall be the
responsibility of the Contractor.
Provided is typical lead-based paint waste information which provides typical chemical and physical
properties of paint removal waste based on previous testing, as follows:
Lead-Based Paint Waste Profile: Lead-based paint waste generated by the removal of paint
consists of a mixture of abrasive blast media such as boiler slag or steel grit and paint chips. This
supplemental information about the waste is provided in accordance with Resource Conservations
and Recovery Act (RCRA) regulations. This composition profile does not include waste resulting
from removal by chemical strippers for which the resulting waste will contain components of the
stripper. Based on the knowledge of the process and the resulting waste material, and on previous
testing of typical waste by independent laboratories approved by the NYS Department of health, this
composition waste material information has been developed for typical lead-based paint waste.
353 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Process Generating Waste: The waste results from removal of lead-based coatings from painted
structures, typically steel bridges, by abrasive blasting, manual, shrouded mechanical, or high-
pressure (hp) water methods. The North American industry Classification System Code (NAICS)
typically assigned for the site is 23731-Highway, Street, and Bridge Construction.
Composition: To the Department’s knowledge, the waste does not contain PCBs, pesticides,
cyanides, organic TCLP constituents, dioxins, asbestos, ozone depleting substances, volatile organics
or greater than 1000 ppm halogenated organic compounds. The waste is not a RCRA reactive,
corrosive or ignitable, or source-listed or chemical product-listed waste. It is not radiological,
etiological, explosive, water reactive, or shock sensitive. The specific composition will vary based on
the removal method used, abrasive used, the proportion of paint chips to abrasives and other variables
determined by the Contractor’s operation. For wastes resulting from any chemical stripping of paint,
the Contractor shall consider the components and properties of the stripper and the resulting waste
mixture to characterize the waste.
The waste typically contains the following:
Approximate %
Removal Method Abrasive Paint Chips
Boiler Slag (an amorphous mixture of Fe, Al and Ca silicates) 90-95% 5-10%
Steel Grit (% varies by degree of grit recycling) 40-90% 10-60%
No Abrasive (manual, shrouded mechanical and water methods) 0% 100%
Paint Chips: Paint chips contain basic lead silico chromate, titantium dioxide, chromate dioxide,
magnesium silicate, linseed oil, alkyd resin, fillers, driers, and other miscellaneous materials.
Other Components: Water may be present from water used during removal. Iron oxide (rust, mill
scale) may be present. Animal waste (i.e., feces, guano, nesting materials, etc.) and
dirt/miscellaneous debris may also be potentially present.
RCRA Metals: The waste is presumed to contain lead at levels exceeding the regulatory limit of 5
milligrams per liter (approximately 5 ppm) by the Toxicity Characteristic Leaching Procedure
(TCLP) test for lead (unless contract documents provided for testing to determine lead toxicity
characteristic). Chromium is considered present as an underlying characteristic.
Typical Physical Characteristics:
Physical State – Solid
Color – Black for boiler slag component, or metallic grey/black for steel grit component.
Color varies for paint chips.
Odor – None
pH – Not Applicable
Liquid Flash Point – Not Applicable
Specific Gravity – Approximately 2.7 (boiler slag) and Approximately 7.5 (steel grit)
Bulk Density – Approximately 1.2 kg/l (boiler slag)

shall be determined in accordance with SSPC-PA 2, Paint Application Specification No. 2 -
Measurement of Dry Film Thickness with Magnetic Gages, using a Type 2 fixed probe magnetic
gages. Dry film thickness gauges shall be calibrated over a blasted, approved surface on the structure
using two NIST traceable shims as described in the “two point calibration adjustment” section of
Appendix 2 of SSPC-PA 2. The two shims must be just below and above the recommended thickness
range of the prime coat, or the combined thickness of successive coats, as applicable. DFTs of the
intermediate and finish coats shall be determined by subtracting the average DFT readings of the
previous coat(s) from the actual DFT reading. An average DFT value shall be recorded and
calculated for every 1000 square feet prepared. The average shall be calculated using a minimum of
5 spot measurements as defined by SSPC-PA2. At least one of the spot measurements shall be
performed on the bottom face of the bottom flange of stringers, girders or floor beams if these
elements are in the work area.
Areas failing to meet the specified minimum dry-film thickness shall be top coated with the same
paint to produce the total dry-film thickness required. The top coating must be performed within the
paint manufacturer’s specified recoat window.
The Engineer may require any area exceeding the manufacturer’s recommended dry-film
thickness to be blast cleaned to the SP-10 condition.
Slip Critical Connections. The policy for coating slip-critical contact surfaces is specified in the
New York State Steel Construction Manual. All metal to metal, slip-critical contact surfaces shall
not be painted unless specified in the Contract Documents and allowed by the New York State
Steel Construction Manual.
G. Painting Schedule. Primer shall be applied to approved, abrasive-blasted surfaces within
8 hours of the final cleaning operation. If the Contractor fails to apply primer to the surface within
8 hours of cleaning, the surface shall be restored in accordance with the SP-10 requirements, at no
additional cost to the State.
To prevent intercoat adhesion failure, recoating must be performed within the manufacturer’s
recommended recoat window, or 14 days, whichever is shorter. If the contractor fails to recoat within
362 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
the specified time period, the surface to be painted shall be cleaned and abraded, in accordance with
manufacturer’s recommendations, to ensure adhesion of the following coat at no additional cost.
If the steel has become dirty between coats, the Contractor shall wash the structure at no
additional cost to the State.
Manufacturer’s recommendations shall be observed for cure to handle, and cure to top coat
schedules.

c. The surface temperature is less than 5°F above the dew point.
2. Steel Cleanliness and Profile. All structural steel surfaces shall be blast cleaned to SSPC SP-
10, Near-White Metal.
The anchor profile shall be measured in accordance with ASTM D4417, Method C. The
Contractor shall ensure that the anchor profile is within the range indicated on the paint
manufacturer’s data sheets. The profile, at a minimum, shall be measured five times in various
locations every 2000 square feet prepared and once per work shift, unless otherwise ordered by
the Engineer. The anchor profile shall not exceed 4 mils unless approved by the Engineer. The
Engineer may approve a profile greater than 4 mils if an area is severely corroded or pitted. If the
Contractor exceeds the 4 mils profile, the Contractor will be required to measure the profile using
extra-coarse-plus replica tape and apply an additional mist coat of primer in accordance with
manufacturer’s recommendations to obtain a minimum 2 mils film build over the profile peaks, at
no additional cost to the State.
All fins, tears, slivers, flame-cut edges, burred and sharp edges that are present or occur
during the blasting operation shall be removed by grinding, and then the area shall be reblasted to
provide the required profile.
Special attention shall be given to the edges of beam flanges, angles and plates, bearings,
rivets, the heads of nuts and bolts, structural steel surrounding bridge joints, and similar surfaces
that are marginally accessible and difficult to clean.
Upon completion of blast cleaning and prior to inspection, the containment shall be
vacuumed and the cleaned surfaces shall be free of all blasting products and paint debris.
Surfaces shall be free of all abrasive prior to inspection. Surfaces shall be cleared of all foreign
matter by means of oil-free, moisture-free, compressed air or vacuum systems
All cleaned surfaces will be inspected by the Engineer prior to painting. Any areas that are
painted before being inspected shall be cleaned and restored to the SP-10 standard and repainted
at no additional cost to the State. If the cleaned surface begins to rust or becomes contaminated
in any matter prior to applying primer, the surface shall be restored to SP-10 standard.
3. Steel Grit. The recyclable abrasive shall be cleaned of all paint, chips, rust, mill scale, and
other foreign material after each use, prior to reuse. The cleanliness of the recycled abrasive
during use shall be confirmed in accordance with SSPC-AB2. The Contractor shall execute,

work shall be removed by vacuuming using HEPA-filtered vacuums. A HEPA filter shall be
defined as a filter that is at least 99.97% efficient for particles that are 0.3μm in diameter, or
larger.
6. Equipment. All equipment and compressors used in the cleaning operation shall be equipped
with filters and traps to prevent moisture, oil, and other contaminants from being deposited on
clean surfaces. The air cleanliness shall be verified by the Contractor with the white blotter test
in accordance with ASTM D4285 at least once per shift for each compressed air system.
7. Cleaning Area. The area cleaned shall be limited to that which can be cleaned, inspected and
prime coated within a 10-hour period. Cleaned areas shall be inspected by the Engineer prior to
priming. Areas that exhibit flash rusting or fail to meet the local standard prior to painting shall
be re-cleaned to the approved standard at no additional cost to the State.
C. Visual and Project Standards. The Contractor shall prepare at least one project cleaning standard
for each representative area on the structure that is being prepared for painting. Multiple standards
may be required if the cleaned steel differs significantly from the photographic standards due to
surface conditions, or other factors such as distance of the standard from the work area.
The prepared cleaning standard shall conform to SSPC VIS 1, "Guide and Reference
Photographs for Steel Surfaces Prepared By Dry Abrasive Blast Cleaning" Pictorial Standard as
applicable, and shall be approved by the Engineer before the start of general cleaning work. Each
cleaning standard shall be at least 12 x 12 inches in size, and shall be located in an area of the
structure that is easily accessible, and approved by the Engineer. The Contractor shall protect the
work standard from corrosion and contamination throughout the duration of work by applying a clear
coat of polyurethane. At the completion of cleaning work, the cleaning standard shall be cleaned and
painted. If the project standard becomes deteriorated, or otherwise ineffective, it shall be
reestablished at no additional cost to the State. In case of a dispute over the visual standard, the
written standard shall take precedence.
573-3.03 PAINTING. The Contractor shall apply three full coats of new paint and one stripe coat to all
surfaces cleaned to SP-10. The paint shall be applied in the following order: primer, intermediate coat,
stripe coat, and the finish coat. All steel surfaces within 6 feet of a bridge joint shall receive an additional
full coat of intermediate paint.

greater than or equal to 40oF and rising. Paint shall not be applied when surface or ambient
temperatures are greater than 100oF. If the temperature range listed on the manufacturer’s data sheets
is more restrictive, the manufacturer’s range shall be used. The use of accelerator additives is
prohibited. No paint shall be applied unless the receiving surface is absolutely dry.
Paint shall not be applied when the relative humidity is more than 85% or the surface temperature
is less than 5oF above the dew point. If manufacturer’s requirements are more restrictive then they
shall be followed. No paint shall be applied during rain or when rain is forecast to occur by the
National Weather Service for the project location during painting operations. All painted surfaces
shall be protected from direct exposure to rain for the time interval recommended by the paint
manufacturer for proper cure. The Contractor shall observe the dew point and humidity restrictions
listed on the manufacturer’s data sheets.
If an epoxy coating is exposed to temperatures or humidity conditions outside of the
manufacturer’s recommended values prior to cure, all affected surfaces shall be visually examined for
greased or oily surfaces which may have formed. The Engineer may require the Contractor to use a
commercially available amine blush test kit at locations chosen by the Engineer. If testing indicates
the presence of an amine blush or if there is any oily film on the surface, the surfaces shall be cleaned
and prepared for topcoating in accordance with paint manufacturer’s recommendations at no
additional cost to the State.
B. Paint Mixing. All paint shall be thoroughly mixed with mechanical mixers in accordance with
the manufacturer's recommendations. After mixing, the bottom of the container shall be free of any
unmixed pigment prior to use.
C. Solvents and Thinners. Paint may be thinned if recommended by the manufacturer and approved

of all areas to be painted shall be performed first, followed by power-tool cleaning of areas demonstrating
corrosion of the steel substrate to remove all paint, rust, rust scale, and mill scale, as per SSPC SP-11,
Power Tool Cleaning to Bare Metal or SSPC SP-10, Near-White Metal Blast Cleaning as applicable. If
heavy deposits of rust and scale are present, they shall be removed by hand or power tool prior to pressure
washing. Areas of tightly adhered coating to remain shall be abraded to provide an anchor profile for
overcoat paint. Large deposits of bird droppings shall be removed prior to pressure washing.
A. Pressure Washing and Solvent Cleaning. All steel surfaces to be painted shall be pressure
washed, using an operating pressure range of 1800 to 2000 psi, a minimum flow of 3.5 gal/minute,
and a water temperature of 185ºF to 200ºF. The nozzle shall be held at a distance of 6 to 12 inches
from the steel surface. Pressure washing shall only be allowed when ambient air temperatures are
greater than 40°F and rising. In no case will pressure washing be conducted when spent wastewater
could freeze on roadway or bridge surfaces or in any other way create a hazardous situation. The
washing is intended to remove contaminants from the surface, not to remove tightly adhered paint.
Oil and grease shall be removed by solvent cleaning as described in SSPC SP1, Solvent Cleaning.
The areas shall be pressure washed again following this cleaning.
When the washing is completed, the cleaned surfaces shall be free of dust, dirt, oil, grease, animal
waste, salts, and other debris

The surface temperature is less than 5°F above the dew point.
2. Steel Cleanliness and Profile. Surfaces which have become visibly corroded shall be cleaned
in accordance with SSPC-SP 11 or SSPC-SP 10, as applicable. Areas where the existing paint
has peeled, flaked, blistered, or otherwise become deteriorated shall be cleaned until only sound
paint, tightly adherent paint remains. These areas need not be cleaned to SP-11 or SP-10 if the
damage does not extend to the steel surface and corrosion of the steel substrate or the mill scale is
not evident.
Equipment used shall produce an anchor profile meeting the manufacturer’s requirements as
reported on the manufacturer’s data sheets. The anchor profile shall be measured in accordance
with ASTM D4417, Method C.
Special attention shall be given to the edges of beam flanges, angles and plates, bearings,
rivets, the heads of nuts and bolts, structural steel surrounding bridge joints, and similar surfaces
that are marginally accessible and difficult to clean.
The edges of intact paint shall be feathered back and the adjoining paint must be tightly
adhered. Ragged or lifting edges on adjoining paint will not be allowed. Adherence will only be
considered satisfactory if the adjoining paint is smoothly feathered back, and cannot be removed
by lifting with a dull putty knife.
3. Vacuuming. The vacuum assembly on all tools shall be capable of containing all visible dust
and debris produced by the operation of the cleaning equipment. Air passing through the vacuum
assembly shall be exhausted through a HEPA filter. A HEPA filter shall be defined as a filter that

A. This work shall consist of removing the top surface of structural slab concrete. Removal shall be done
by scarification to the following limits, unless a greater depth is indicated on the plans:
• Minimum of 1/4 inch
• Maximum of 1/2 inch
B. After scarification, if a structural slab survey is required, the surface to be surveyed shall be cleaned
sufficiently to allow the survey to be taken. The Engineer will determine if the surface is cleaned
sufficiently to allow performance of the necessary delamination and potential survey tests.
C. All removed materials shall be transported from the work site and disposed of or disposed of in an
area on the job site approved by the Engineer.
579-1.02 Exposure of Reinforcing Bars
A. Definitions
1. Bar Mat. That combination of transverse and longitudinal reinforcing steel placed with the
structural slab to absorb stresses. Structural slabs generally contain two bar mats; an upper mat
and a lower mat.
2. Upper Mat. That bar mat closest to the existing top surface of the structural slab. Only the
upper mat is relevant to this work, except in localized areas.
3. Localized Area. An area where full depth removal and subsequent patching will be done as
part of this work. For the work of this section a localized area shall not exceed 25 sf. The sum of
the localized areas shall comprise no more than five percent (5%) of the structural slab area to be
prepared.
B. The work shall consist of structural concrete removal from the periphery of the upper mat
reinforcing bars to provide a minimum clearance of 1 inch between the reinforcing bar surface and
383 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
the remaining concrete surface. In addition, the Engineer may order the removal of other concrete.
(Refer to 579-3, Construction Details).
C. All work performed under the requirements of this subsection shall not extend beyond a plane
which is 5 inches below the original top of slab, except for localized areas.

operations to material that is to remain shall be repaired, or the material replaced as determined by the
Engineer. All repair and replacement work shall be done in a manner satisfactory to the Engineer.
579-3.01 Structural Slab Scarification. Scarification of designated areas shall be accomplished with a
power operated scarifier. Inaccessible areas will be scarified with pneumatic hammers.
579-3.02 Reinforcing Bar Exposure
A. Concrete shall be removed from the uppermost reinforcing bars of the structural slab to the limits
designated by §579-1.02B. The Contractor may remove concrete, to the designated minimums, from
around both sets of bars in the upper mat.
B. If concrete is removed only from the periphery of the uppermost bar, removal shall be done in
accordance with those details indicated on the plans.
C. If the Contractor chooses to remove concrete from the periphery of both bars of the upper mat, or if
the Engineer determines that:
• The lower bar is corroded; OR
• The concrete around the lower bar is deteriorated; OR
• Delamination extends to the level of, or below, the lower bar; OR
• The lower bar is debonded;
384 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
then the concrete shall be removed from the periphery of the lower bar in accordance with the details
indicated on the plans.
D. At locations where deteriorated concrete extends beyond the minimum removal limits, the Engineer
will order its removal. The Engineer will be the sole determiner of what constitutes deteriorated concrete.
This ordered removal shall be part of this work, except that removal of deteriorated concrete below the
limit established by §579-1.02C, shall be part of this work only within the limits of localized areas.
Locations where concrete is removed beyond minimum limits, lacking specific orders from the
Engineer directing such removal, will be designated as damage locations. All damage locations shall be
repaired in a manner satisfactory to the Engineer, at no additional cost to the State.
E. At localized areas, the Engineer may order concrete removal below the plane established by §579-
1.02C. When such removal reaches the uppermost bar of the lower reinforcing bar mat, removal shall be
continued until full depth removal is achieved.
F. Care shall be exercised when removing concrete to avoid damaging reinforcement, or other materials,
which are to remain in place. Reinforcing steel damaged by the Contractor's operations shall be replaced
with new reinforcing steel of the same size, appropriately spliced. Reinforcing steel splices shall be made
in accordance with the details shown on the plans. Other materials designated to remain in place, which
are damaged by the Contractor's operations, shall also be replaced.
579-3.03 Full Depth Patches. Refer to the details indicated on the plans.
A. Immediately prior to placing new concrete, the reinforcing bars and the edges of the existing structural
slab, which will be in contact with new concrete, shall be blast cleaned. Forms shall be drawn tightly.
Preparation and formwork shall be approved by the Engineer prior to any concrete placement. “After
blast cleaning has been accepted, thoroughly wet the structural slab surface and all porous surfaces to be
in contact with new concrete for at least 12 hours immediately prior to placement. Remove all standing
water with oil-free compressed air, and protect the surface from drying, so the concrete remains in a
saturated surface dry condition when placing bonding grout.
B. Concrete shall be placed and consolidated in accordance with the requirements of §555-3.04. The
uppermost surface of the concrete patch shall be level with the highest of the surrounding prepared
surfaces. The uppermost surface shall be intentionally roughened. The Engineer may require that a
coarse textured drag be used on the plastic concrete surface.
C. Concrete shall be cured, in a manner approved by the Engineer, for a minimum of 72 curing hours
prior to any other concrete placement work in contact with the curing concrete. A curing hour is defined
as any hour, starting from the hour of placement, during which the ambient air temperature at the concrete
surface remains at, or above 45 F as measured by a recording thermometer. Curing shall be done by
means of quilted covers (§711-02), or plastic coated fiber blankets (§711-03). Quilted covers, if used,
shall be kept wet during the entire curing period. The use of curing compounds shall not be allowed.
579-3.04 Hydrodemolition Equipment. Hydrodemolition equipment, if approved by the Engineer, shall
be subject to the following:
A. Water Filtration and Disposal. At least two weeks prior to the employment of any
hydrodemolition equipment, the Contractor shall submit to the Engineer, for approval, a
comprehensive plan for the filtration and disposal of hydrodemolition water.
This plan shall ensure, to the extent practical, that all debris particles will be removed from
hydrodemolition water, prior to its being introduced into any lake, river, stream, or any drainage
system which empties into a lake, river or stream.
The Contractor is specifically notified that use of the existing bridge drainage system for
hydrodemolition water disposal will not be permitted.
385 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
B. Water Retention. Hydrodemolition water shall be prevented from running onto, or over all
portions of the project site not immediately subject to hydrodemolition work. In addition, the
Contractor shall provide shielding, acceptable to the Engineer, that protects traffic and prevents all
debris from escaping the immediate work location. A comprehensive plan for accomplishing these
requirements shall be submitted to the Engineer, for approval, at least two weeks prior to the
beginning of any hydrodemolition work.
The Contractor is specifically notified that use of the existing bridge drainage system, for this
purpose, will not be permitted.
The plan for this work may be submitted as part of the requirements of §579-3.04A.
C. Adherence. Once approved, the water filtration and disposal, as well as the water retention plans
shall be strictly adhered to by the Contractor. Should the Engineer determine that these plans are not
being followed as approved, the Contractor will be required to immediately cease work until the
conditions are rectified in a manner satisfactory to the Engineer.
Should the Contractor fail to rectify the situations to the Engineer's satisfaction, the Engineer
may, with the concurrence of the D.C.E.C., require the Contractor to use equipment other than
hydrodemolition equipment.
No extension of time will be granted, nor will any additional compensation be granted, for either
the ceasing of work, or the substitution of equipment, if either one is required as a result of the
Contractor's failure to follow the approved plans.
D. Debris Removal. All debris shall be removed quickly enough to prevent rebonding of the debris
to the concrete surface. All debris which rebonds shall be removed in a manner satisfactory to the
Engineer at no cost to the State.
Material designated to be left in place, which is damaged by rebonded debris removal work, shall
be repaired in a manner satisfactory to the Engineer at no cost to the State.

582-3 CONSTRUCTION DETAILS
582-3.01 Repair Determinations. The choice of replacement material will be indicated on the plans,
determined by the Engineer, or determined by the contractor. The Contractor's determinations shall be
made in accordance with the criteria of this subsection, and only in the absence of directions from the
plans, or the Engineer. The Contractor's determinations shall be approved by the Engineer prior to the
actual performance of the work.
A. Horizontal or Essentially Horizontal Locations. Class A, Class D or Class DP concrete shall be
used. Class A concrete shall be placed only at locations where removal depths average greater than 5
inches. Class D concrete shall be placed only at locations where removal depths average between 1 ½
and 5 inches. Class D or DP may be used for pedestal repairs when access is limited and where
placement dimensions are greater than 1½ inches but do not exceed 12 inches. Average depth shall
be determined by a measurement procedure acceptable to the Engineer.
B. Vertical or Essentially Vertical Locations. Class A concrete, Class D concrete, or approved
patching material shall be used. Concrete classes shall be restricted to the depth limitations noted for
horizontal locations. Patching material shall be placed at locations where removal depths average
between 1/2 and 1 1/2 inches. Average depths shall be determined by a measurement procedure
acceptable to the Engineer.
C. Overhead. Class A, Class D or approved patching material shall be used when formwork is
provided. Concrete classes shall be restricted to the depth limitations noted for horizontal locations.
Approved patching material may be used without formwork provided lift thicknesses do not exceed 1
inch. Anchoring devices shall be used when patching material is used for repair depths of 1½ inches
or greater.
D. Pockets. Locations, within locations of 1 1/2 inches in average depth or less, which exceed this
average depth, shall be filled with Class A, or Class D, concrete in accordance with the limitations
outlined under horizontal locations.
582-3.02 Removal of Unsound Concrete. All unsound concrete shall be removed to a sound surface as
determined by the Engineer. If called for on the plans, the existing concrete shall be saw-cut to obtain a
straight joint between the existing concrete and the new material. Care shall be exercised while removing
the unsound concrete so as not to damage materials which are to remain in place. Exposed reinforcement
389 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
remaining in place shall be cleaned in accordance with the requirements of §584-3.02A. Chipping
hammers shall meet the requirements of §580-3.02.
A. Removal for Concrete Replacement. The minimum depth of removal shall be the greater of the
following:
• A depth no less than 1 1/2 inches from the rear most point of reinforcement to sound concrete.
• The depth necessary to reach sound concrete.
Should the removal depth exceed 6 inches, the Engineer may order supplementary anchoring as
part of the replacement procedure. The sides of the cavity shall be made at a slight angle, so that the
width of the base of the cavity is greater than the opening at the surface, thereby providing a key.
B. Removal for Patching material Replacement. Feather edges shall not be permitted. The
minimum patch depth shall be 1/2 inch as measured from the theoretical plane of the original concrete
surface.
582-3.03 Preparation of Surface
A. All surfaces receiving new material shall be blast cleaned in accordance with the requirements of
§584-3.02.
B. Bar reinforcement shall be placed at the location indicated on the plans, and at all additional locations
determined by the Engineer.
C. Existing reinforcement, which, in the Engineer's opinion, has lost significant section, shall be repaired
in a manner satisfactory to the Engineer.
D. Bar placement, and bar repair work directed by the Engineer will be paid for separately.
582-3.04 Placement. Air clean the surface with oil-free compressed air. After the surface preparation has
been accepted, every effort should be made to thoroughly wet the concrete surface, and all porous
surfaces to be in contact with new concrete, for 12 hours. This may be accomplished by continuous
wetting with soaker hoses or the use of burlap/burlene/etc. where moisture can be maintained. If, in the
opinion of the Engineer, conditions or the situation prohibits this, then the surfaces should be wetted for
as long as possible. Surfaces must be wetted by a means acceptable to the Engineer using potable water.
The Contractor shall remove any puddles of free standing water with oil-free compressed air, and
protect the surfaces from drying, so the existing concrete remains in a clean, saturated surface dry
condition until placement of the new concrete. No material shall be placed if the ambient air, or
concrete surface temperature is at, or below 45oF.
A. Concrete Placement. All concrete placements shall be in accordance with the applicable
requirements of the following subsections:
555-3.02, 555-3.03A, 555-3.04, 555-3.06, 555-3.07, 555-3.08.
If formwork configuration, or clearances between formwork, steel and existing concrete are such
that Class A, or D, concrete cannot be placed without voids, or honeycombing, the Contractor may,
with the Engineer's permission, use an approved high range water reducer to increase the concrete's
workability. Approved high range water reducers appear on the Department's Approved List.
The high range water reducer shall be added at the work site only and shall be dispersed
uniformly throughout the plastic concrete. The Engineer shall approve the Contractor's dispersal
methods and devices prior to their actual use.
The high range water reducer shall be added only after the concrete has reached the proper slump
and contains the required quantity of air. No more than two additions of the admixture shall be made,
390 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
and the manufacturer's maximum dosage rate shall not be exceeded. After the admixture has been
added, the concrete shall be mixed an additional 30 revolutions. The second admixture addition shall
be made only after the 30 revolutions required for the first addition have been completed. It is the
responsibility of the Contractor to ensure that concrete slump does not exceed 9 inches, and air
content remains within specification requirements. Plastic concrete mixes failing to meet the
foregoing requirements will be subject to rejection. Replacement will be done at the Contractor's
expense.
The Engineer may allow high range water reducer to be added at the concrete batching facilities.
Consideration for this procedure will be undertaken only after the Contractor has clearly
demonstrated the capability of providing concrete which meets the requirements of this subsection.
B. Vertical and Overhead Patching Material Placement. Patching material shall be prepared in
accordance with the directions provided by the manufacturer. The Engineer shall be given two copies
of the manufacturer's printed instruction at least two weeks prior to the start of all patching work.
This shall include the mixing proportions and the mixing method. The manufacturer's literature shall
be consulted for surface preparation and priming instructions. The material shall be troweled on in
layers, the thickness of which depends on the material consistency and the location and profile of the
surface to which it is applied. However, lift thickness in excess of 1 inch will not be permitted
without the use of anchoring devices or formwork at overhead locations. Special curing procedures
are generally not required, except under conditions of high heat, low humidity, or strong winds, as
defined by the manufacturer. The manufacturer should be consulted for specific curing procedures
under these adverse conditions.
582-3.05 Form Removal. Form removal shall be in accordance with §555-3.09 with the following
exception:
Forms shall be removed from thin concrete placements 24 curing hours after placement has been
completed unless the Engineer determines the concrete is not strong enough to withstand damage. For
purposes of this subsection, a thin concrete placement begins at the outermost surface of the new concrete
and generally terminates at, or before, the midpoint of the main reinforcing steel. Concrete may be
removed and replaced completely around one or two main reinforcing steel members to a depth no greater
than 1 inch from the innermost surface of those members and still be considered a thin concrete
placement. Main reinforcing steel members include reinforcing bars, but not spiral reinforcement or
stirrups. Curing procedures shall be implemented immediately upon form removal.
582-3.06 Curing. Curing shall be performed according to the following:
A. Concrete. This shall be done in accordance with §555-3.08.
B. Vertical and Overhead Patching Material Curing. Manufacturer's recommendations for curing
shall be followed for the patching material applications.

replacement with shotcrete where indicated in the contract documents and where ordered by the Engineer.
The Contractor has the option of using either the Dry Mix Process or the Wet Mix Process.
583-1.02 Definitions
A Shotcrete. This is mortar conveyed through a hose and pneumatically projected at high velocity
onto a surface.
B. Dry Mix Process. This is a process in which the dry cement-sand mixture is carried by
compressed air to the nozzle where water is injected and the resulting mixture is jetted from the
nozzle at high velocity onto the surface to be shotcreted.
C. Wet Mix Process. This is a process in which all the ingredients including water are thoroughly
mixed and then jetted from the nozzle at high velocity onto the surface to be shotcreted.
392 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
D. Delivery System. This consists of the nozzle, water ring or air ring, and any necessary valves,
connected to the delivery hose.

Hook Bolts Inserted in Expansion Bolt Anchors ASTM A307 Grade A
NOTE. The wire fabric shall be galvanized in accordance with ASTM A641M regular coatings. The wire fabric shall be
fabricated from No. 12 wire spaced 2 inches (nominal) in each direction or No. 10 wire spaced 3 inches (nominal) in each
direction. Wire used shall have a minimum yield strength of 35 ksi.
583-2.01 Equipment
A. Batching and Mixing Equipment. The mixing equipment shall be capable of thoroughly mixing
the materials in sufficient quantity to maintain placing continuity.
B. Air Supply. The compressor shall be of adequate capacity to maintain a sufficient, constant nozzle
velocity for all parts of the work while simultaneously operating a blow pipe for cleaning away
rebound. The air hose shall be equipped with a filter to prevent any oil or grease from contaminating
the shotcrete.
C. Delivery Equipment
1. Dry Mix Process. The delivery equipment shall be capable of delivering a continuous, smooth,
uniformly mixed material to the nozzle. The nozzle shall be equipped with a water ring and valve
to permit adjustment of the water. The water added to the dry mix material at the nozzle shall be
maintained at a pressure at least 16 psi greater than the air pressure. The nozzle shall be capable
of delivering a conical discharge stream.
2. Wet Mix Process. Only pneumatic-feed type of delivery equipment will be allowed. Positive
displacement type of equipment will be allowed pending a qualification test prior to the beginning
of the work, which will also be the qualification test for the operator. The nozzle shall be
equipped with an air ring for injecting compressed air into the material flow.
583-2.02 Qualification Test. If encasement of reinforcing bars is required, this test shall be performed to
qualify the shotcrete operator and the equipment, prior to beginning work. Each shotcrete operator shall
be qualified by constructing a 2 x 2 foot test panel fabricated to duplicate the project shotcreting.
Reinforcement shall be placed in the panel to provide a minimum 1 inch (front and rear) embedment and
be of the same size and spacing encountered in the structure. Panels shall be shot in the vertical,
horizontal, and overhead positions as expected to be encountered. After setting, the test panel shall be
broken open in a manner approved by and in the presence of the Engineer, to verify the reinforcement
embedment. If voids are discovered, the work shall not proceed; additional panels shall be constructed
until results acceptable to the Engineer are achieved. Small non-interconnected voids, as determined by
the Engineer, shall not constitute failure.
393 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Additional qualification panels will be required whenever, in the opinion of the Engineer, the
shotcrete operation significantly changes.
583-3 CONSTRUCTION DETAILS
583-3.01 Preparation of Surfaces. All unsound concrete shall be removed until there are no offsets in
the cavity which would cause an abrupt change in thickness, except for a transition from above to below
reinforcement. Minimum 1/2 inch square shoulders shall be left at the perimeter of the cavity. The final
cut surface shall be sound and properly shaped. The sound surface shall be blast cleaned. Abrasive
material used for blastcleaning shall contain no more than one percent free silica by weight. Air clean the
surface with oil-free compressed air. After the surface preparation has been accepted, every effort should
be made to thoroughly wet the concrete surface and all porous surfaces to be in contact with new concrete
for 12 hours. This may be accomplished by continuous wetting with soaker hoses or the use of
burlap/burlene/etc. where moisture can be maintained. If in the opinion of the Engineer conditions or the
situation prohibits this then the surfaces should be wetted for as long as possible. Surfaces must be
wetted by a means acceptable to the Engineer using potable water. The Contractor shall remove any
puddles of free standing water with oil-free compressed air, and protect the surfaces from drying, so the
existing concrete remains in a clean, saturated surface dry condition until placement of the new concrete.

NOTE: 1. Bolt diameters may be increased but not decreased. Spacing may be decreased but not increased.
No material shall be placed if the ambient air, or concrete surface temperature is at, or below 45oF.
Reinforcement may consist of either existing reinforcing bars or welded galvanized wire fabric,
depending on the conditions and shall be clean and free from loose mill scale, loose rust, oil or other
coatings that interfere with bonding.
Chipping hammers shall meet the requirements of §580-3.02.
Sufficient clearance shall be provided around the reinforcement to permit complete encasement with
sound shotcrete. The minimum clearance between the reinforcement and the form or other backup
material shall be 1 inch.
Where the chipped area is equal to or less than 2 inches in depth, the use of wire fabric or mechanical
concrete anchors will not be required except for overhead surfaces. Where the chipped areas are
overhead, and are 1 inch in depth or greater, galvanized wire fabric and mechanical concrete anchors shall
be used. Mechanical concrete anchors shall be placed as required by Table 583-1.
Where the chipped area is over 2 inches in depth and existing bar reinforcement is available,
galvanized wire fabric shall be attached to the bars with tie wires. If existing bar reinforcement is not
394 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
available, wire fabric shall be installed by means of mechanical concrete anchors in accordance with the
requirements of Table 583-1.
Wire fabric shall be cut in sheets of the proper size and shall be carefully bent in such a manner as to
follow closely the contours of the areas to be repaired. The wire fabric shall be securely tied to the hook-
type bolts or the reinforcing bars.
Where sheets meet, they shall be lapped a minimum of 4 inches and shall be securely fastened
together.
Expansion bolt anchors shall be placed in holes drilled in the existing concrete surface to the diameter
and depth recommended by the manufacturer of the expansion bolt anchors. Hook-type bolts of the
proper length shall be inserted and securely attached to the expansion bolt anchors so as to provide a
positive connection to sound concrete.
Where the chipped area is 6 inches or greater in depth, the Contractor shall place galvanized wire
fabric in layers 4 inches apart.
Where it is necessary to place more than one layer of galvanized wire fabric in an area to be repaired,
the innermost layer shall be covered by a shotcreting prior to the installation of the next outermost layer.
Existing reinforcement which has lost significant section shall be repaired in a manner satisfactory to
the Engineer as extra work.
583-3.02 Preparation of Materials
A. General. The sand shall be measured either by volume or weight, by means of batch boxes
approved by the Engineer, or in a proportioning plant approved in accordance with section 501,
Portland Cement Concrete - General. Wheelbarrows or shovels will not be permitted for measuring.
The same source of sand shall be used throughout each structure.
B. Dry Mix Process. Dry mix shotcrete shall be composed of one part of cement to three to four and
one-half parts of sand.
Prior to mixing, the moisture content of the sand shall be between 3 and 6%. The sand shall be
dampened or dried as required to bring the moisture within these limits.
A wetting agent approved by the Engineer may be used at the Contractor's option in the dry mix
process.
Sand-cement mixtures shall be applied within 75 minutes of the time the sand initially contacts
the cement. Sand-cement mixtures which exceed the 75 minute limit shall not be incorporated in the
work. They shall be disposed of in a manner acceptable to the engineer.
C. Wet Mix Process. Wet mix shotcrete shall be composed of one part of cement to three parts of
sand. The cement, sand and water shall be premixed to a desired consistency and in accordance with
§501-3.03, Handling, Measuring and Batching Materials, and §501-3.04, Concrete Mixing,
Transporting and Discharges - General Requirements.
583-3.03 Placement
A. Weather. Shotcrete shall not be applied during any precipitation which is of sufficient intensity to
cause the placed shotcrete to run. Shotcrete shall not be placed during a wind that disrupts the nozzle
spray.
Shotcrete shall not be applied when the ambient air temperature is below 45 F unless it is placed
in accordance with §555-3.08C.2., Provision of External Heat. Receiving surfaces shall be heated to,
and maintained at, approximately 45 F by a method approved by the Engineer before shotcreting
operations begin. Under no conditions shall shotcrete be applied against surfaces upon which any
frost adheres.
395 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
B. Application. Before starting to shoot, precautions shall be taken to protect property in the area.
Adjacent construction, openings, shrubbery, and all areas that might be discolored or damaged by
rebound, cement, water or dust must be covered with tarpaulins or plastic sheets to protect them from
damage.
When projecting the shotcrete, the stream of flowing materials shall be directed from the nozzle
as nearly at a right angle as possible to the surface being treated, and shall be held uniformly at the
same distance, less than 5 feet away from the surface at all times. Manufacturer's recommendations
shall be followed. The size of the nozzle shall be consistent with the manufacturer's recommendation
for the maximum size of the sand used. The use of rebound material shall not be permitted.
Shotcrete on vertical and overhead surfaces shall be built up in 3/4 inch maximum layers to
prevent sloughing in heavy applications. Succeeding layers shall be applied just prior to the initial set
to maintain a good bond.
When encasing reinforcing steel, the stream from the nozzle shall be directed at an angle so as to
fill the space behind the bars. An air jet shall be used to blow out any rebound ahead of the
application of shotcrete. Should any such deposit of sand rebound be covered with shotcrete, it shall
be cut out and removed by the Contractor without compensation.
Ground wires may be installed to establish the thickness and surface planes of the shotcrete build
up. Both horizontal and vertical ground wires may be installed at corners and offsets not clearly
established by exterior corners of walls, column or beam corners, and other locations. They may also
be used as screed guides. Eighteen or 20 gage hard steel piano wire is recommended for this purpose.
Ground wires shall be tight and true to line, and placed in such a manner that they may be further
tightened.
C. Quality Control
1. Test Panels. This test shall be used to determine the physical quality of the shotcrete and shall
be performed immediately before shotcreting operations begin, after each additional 100 sf, and
immediately after operations are ended.
The test panels shall be 12 inches square, 3/4 inch thick plywood boards with galvanized
mesh (1/2 inch square openings) strips projecting 4 inches attached around the perimeter of the
board. The boards shall be erected horizontally, vertically, or overhead, depending on the
anticipated shooting positions. The shotcrete operator shall completely fill the test panel, after
which it shall be screeded or cut with a trowel such that it contains a 4 inches uniform depth of
shotcrete. The test panels shall then be covered with wet quilted covers or wet polyethylene-
coated blankets; put in a shaded, protected place; kept wet and cured for a minimum of seven
days. The test panels shall be sent to the Department of Transportation's Materials Bureau for
testing at fourteen days. Cores will be drilled from the panels and compressive strengths at
fourteen days will be reported to the Engineer. Additional information on the conditions of the
shotcrete such as sand pockets, voids, and laminations will also be reported with the strength
results.
2. Coring. The Contractor shall take a core, at a location determined by the Engineer, from each
structural element, such as pier, abutment, arch, etc., to verify acceptability of reinforcement
encasement. Cores which do not contain reinforcing bars will not be used to determine
encasement acceptability. If interconnected voids are found, the structural element represented
by that core shall be rejected. All rejected shotcrete shall by repaired or replaced at the
Contractor's expense. Repair methods shall be proposed by the Contractor for approval by the
Engineer. The Contractor may take additional cores at locations approved by the Engineer to
establish the limits of rejected work. The additional coring shall not jeopardize the design
integrity of the structural element. If additional cores are not taken, all work on that structural
396 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
element shall remain rejected. Core holes shall be patched with an applicable concrete repair
material from the Approved List.
D. Finishing. The natural gun finish will be sufficient unless the plans call for one of the following
finishes:
1. Screed Finish. After the surface has taken its initial set, excess material outside the forms and
ground wires shall be sliced off with a sharp-edged cutting screed. After screeding, the ground
wires shall be removed.
2. Broom Finish. This type of finish may be applied after screeding.
3. Flash Coat Finish. This is a thin surface coating containing finer sand than normal, and the
application nozzle is held well back from the work. This finish shall be applied to the surface as
soon as possible after screeding.
Any of the remaining three types of finish may be applied following flash coat:
a. Wood Float Finish. This gives a granular finish.
b. Rubber Float Finish. This gives a coarse finish.
c. Steel Trowel Finish. This gives a very smooth finish.
E. Curing. Curing shall be in accordance with §555-3.08, Curing, and the following modifications:
• All curing covers shall be pre-wet and kept wet during the entire curing period in a manner
satisfactory to the Engineer.
• Curing compounds shall be applied twice. The second application shall be done when the first
application has become tacky. The second application shall be done at a right angle to the first
application. The rate of each application shall be that given in §555-3.08A.
583-4 METHOD OF MEASUREMENT. The quantity to be paid for under this item will be the number
of square feet of finished shotcrete installed. Measurement will be taken as the plane projection of the
finished surface. Measurement shall be made prior to the placement of shotcrete.

584-3 CONSTRUCTION DETAILS
584-3.01 Limitation of Operations
A. No structural concrete removal work is permitted in areas adjoining new concrete during the new
concrete's specified curing period.
B. No loads, other than construction loads which are less than 2 tons and approved by the Engineer, are
permitted on areas of the structural slab where concrete has been removed.
C. No loads are permitted on concrete until completion of the specified curing period.
584-3.02 Blast Cleaning
A. Blast clean all surfaces to be in contact with new concrete. Remove all grease and dirt. Remove all
rust and mortar which is not firmly bonded to the surface being cleaned. Rust and concrete deposits
which are firmly bonded and cannot be removed by blast cleaning may remain. A light coating of orange
rust, that forms on steel surfaces after blast cleaning, is not considered detrimental to bond and may
remain. Remove all debris created by blast cleaning.
B. Place reinforcing steel supports and positive-tie-downs at a maximum spacing of 4 feet.
C. Repeat blast cleaning if more than 48 hours pass before concrete placement begins.
584-3.03 Preplacement Wetting. After blast cleaning has been accepted, thoroughly wet the structural
slab surface and all porous surfaces to be in contact with new concrete for at least 12 hours immediately
prior to placement. Remove all standing water with oil-free compressed air, and protect the deck from
drying, so the concrete remains in a saturated surface dry condition.
584-3.04 (Vacant)
584-3.05 Handling and Placing Concrete. §557-3.05 and §557-3.12 with the following:
A. Place concrete only when the ambient air temperature and deck surface temperature (after wetting)
will be below 85 F during the entire placement.
B. Place overlay concrete only if preplacement wetting has been completed on an area large enough to
require one working day for placement, at least one span length.
C. When using concrete transporting devices on a prepared surface, protect exposed reinforcing steel
from deformation and prevent contamination of the surface.
D. If operations are delayed for more than 30 minutes, install a construction dam or bulkhead. If
placement operations are delayed for more than 60 minutes or if the concrete attains initial set,
discontinue placement for at least 48 hours. This restriction does not prohibit continuation of the
placement provided a gap is left in the placement. This gap is to be sufficient in length to allow the
finishing machine to clear the previously placed concrete. Prepare the gap area for concrete placement in
accordance with this specification, after the previously placed concrete, on both sides of the gap, has
cured for 48 hours.
584-3.06 Finishing and Curing
A. Slab Reconstruction Concrete - Separate Placement. §557-3.09 and §557-3.11 with the
following:
401 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
1. For areas less than 25 sf, hand finishing of slab reconstruction concrete is acceptable. For areas
greater than 25 sf, use either a manually driven vibrator equipped power screed from the
Department’s Approved List or the same machine to be used to finish the overlay.
2. Screed to the level of the surrounding concrete. When 100% of the reinforcing steel is exposed,
screed to a minimum 3/8 inch above the reinforcing steel. Roughen the screeded surface with a tining
rake or similar device.
3. Cure concrete with wet burlap for 3 days. Provide uniform continuous wetting until concrete
curing is complete. The wet burlap and curing cover option is not allowed.
4. Blastclean the surface, according to §584-3.02, after the curing period is over, but prior to wetting.
Expose approximately 50% of the surface coarse aggregate, and leave an irregular texture.
B. Overlay Concrete. §557-3.08, §557-3.11, and §557-3.12 with the following:
1. Finish overlay concrete to a minimum depth of 1 1/2 inches and a minimum total cover over top
mat of bar reinforcement of 2 3/8 inches. Use a finishing machine meeting the requirements of this

removed by means of a core drill. The remainder of the drilling shall be done with the rotary impact drill.
407 NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) May 1, 2020 Volume 2
Where plans indicate significant design reinforcement, a non-destructive investigation shall be done to
determine the location of existing reinforcing steel prior to drilling. If after the non-destructive
investigation, reinforcing steel is determined to be in conflict with, or encountered during the drilling
operation, the DCES shall be notified to determine the appropriate course of action.
The Contractor shall not perform drilling with a lubricant, except in this case water is not considered a
lubricant. Drilling methods shall not cause spalling, or other damage to concrete. Concrete spalled, or
otherwise damaged by the Contractor's operations shall be repaired at no additional cost to the State.
Holes shall be surface dry and shall have had all foreign and loose material removed immediately prior
to grout placement. Prior to anchor placement in the grouted hole, all material which might interfere with
bond between the anchor and the grout shall have been removed. This includes, but is not limited to:
moisture, grease, dirt, mill scale and rust. Rust which cannot be removed from the anchor even by vigorous
scrubbing with a wire brush is considered firmly bonded and may remain, unless more specific instructions
are provided in the manufacturer’s installation procedures. The depth of hole and hole diameter shall be in
accordance with the grout manufacturer's recommendation, and shall consider: anchor diameter, strength
of existing concrete, anchor spacing and edge distance. The distance from the bottom of the hole to the
nearest free surface of a structural element, shall be at least 1 5/8 inches or as recommended by the
manufacturer, whichever is greater. The length of any plastic sleeve used as an aid to grout placement shall
not be included in the length of the hole. The Contractor may increase the embedment length beyond that
required by the contract documents if approved by the Engineer, at no additional cost to the State.
Grout shall be stored, mixed, and placed in accordance with the manufacturer's instructions. No grout
shall be placed at a temperature outside the range recommended by the grout manufacturer.
Anchors shall be inserted full depth into the grouted hole and shall be manipulated or rotated in
accordance with the Manufacturer's recommendations to ensure complete coverage of the embedded anchor
with grout. After insertion of the anchor, all excess grout shall be struck off flush with the concrete face.
Care shall be taken to prevent grout from running out of the drilled hole. Should the grout fail to fill the
hole after anchor insertion, additional grout shall be added immediately after insertion of the anchor to
allow a flush strike-off.
If the anchor is inserted in a hole with an axis that is predominantly horizontal, care shall be taken to
prevent grout from running down the face of the concrete.
All uses of Anchoring Materials - Chemically Curing, both permanent and temporary, shall be installed
by a certified ACI/CRSI Adhesive Anchor Installer.
Temporary applications using §701-07 Anchoring Materials - Chemically Curing shall be inspected by
the Contractor every 90 days at a minimum to ensure that the adhesive anchor is performing as intended.
The Contractor shall check for such things as creep of anchor material, movement of the anchors, loose
bolts, loose nuts, etc. Temporary items anchored using §701-07 Anchoring Materials – Chemically Curing
shall be removed or abandoned, in such a way that the anchors are no longer subject to any load upon
completion of their temporary use.
A. Anchor Pull-Out Testing. Table 586-1 Number of Anchors to be Pull-Out Tested gives the
number of anchors (N1) to be tested for any lot size. The Engineer will randomly choose the anchors
to be tested. Testing of anchors in a lot shall not begin until all the anchors in the lot are installed. If
one (N1) anchors fails, N2 indicates the number of additional anchors that must be tested. If only one
anchor fails (N1+N2), the lot will be accepted. If more than one anchor fails, all remaining anchors
must be tested.
A lot size is determined by the Contractor, but must meet the following criteria:
1. A lot size shall not exceed 600 anchors.
2. All anchors in a lot must be installed within a two-month period.
3. Any anchors installed beyond the two-month period set forth in 2 above shall be part of another
lot.
4. A lot shall only include anchors grouted with a single product
5. A lot shall only include anchors of the same type, diameter and embedment depth.
